INSTALLATION INSTRUCTIONS Cont...

For best venting performance, here are some general venting rules:
1. Use only vent systems and components certified for use with this appliance
2. Maintain a minimum of 1” (26 mm) clearance to combustibles from the outside
surfaces of vertical vents and minimum of 1” (26 mm) sides and bottom, and 2” (51mm) from top surfaces of horizontal vents. Always use a wall thimble when passing
through combustible construction.
3. Observe all local code restrictions, if any, regarding the installation of this type of gas
appliance.
4. Observe the vent height and length restrictions given in this manual.
5. Never slope horizontal vents downwards.
6. Maintain at least an upward slope of 1/4” (7 mm) for every 1 ft (305 mm) of
horizontal vent.
7. Terminate the vent with a termination certified for use with this appliance.
8. Support horizontal vent every 3 ft (915 mm) to prevent it from sagging.

INSTALLATION INSTRUCTIONS Cont...
VENT RESTRICTORS FOR TOP VENT INSTALLATIONS
All top vent installations above 20' (6.1 m) require the use of
60% restrictor.
The restrictor is installed in the exhaust of the appliance.

Vent Restrictors
Due to the extra flow produced by certain venting configurations vent restrictors must
be placed in the vent to maintain performance. When your installation requires a vent
restrictor you must remove the flue baffle and install the restrictor in the exhaust box asshown below. The restrictor is fastened in with 2 screws represented by the dottedline in the figure below. Once the vent restrictor has been installed the flue baffle mustthen be re-installed.
Note: The unit must be cooled to room temperature before installing the restrictor.

Figure 4

Page 20

THE CALDERAINSTALLATION INSTRUCTIONS Cont...

WARNING: A minimum clearance of 1” to combustibles must be maintainedon vertical pipe runs and 2” for horizontal pipe runs (sides and bottom 1”)
The rigid vent systems use twist lock connections. The adaptor attached to the unit
connects to the approved venting system. While you are assembling the pipe bear in mind thebest visual appearance. Seams should be aligned and hidden as much as possible. Make sure
you twist the mating section all the way to make a solid connection.
Note: As this system is a sealed system, a high temperature sealing compound must be
used to seal the metal to metal joint.
Apply a bead of high temperature sealant to both the 4”
exhaust and 6-5/8” intake section of the male pipe. The
female section of the pipe/fitting has four indentations
evenly spaced around the pipe. These indentations aredesigned to slide over the male section of the pipe andlocate into the four entry slots of the male section of pipe.
Twist the female section clockwise a quarter turn to fully
lock the sections together.

High
Temperature
Sealant(Mil-Pac / RTV)

Horizontal Wall Vent Terminations
The position of the horizontal vent termination must be positioned to meet all local building
codes (see termination chart on page 45).
Attach the correct length of vertical section pipe and an elbow fitting to the stove.
Mark the center line of the pipe facing the wall (allowing for a 1/4” rise per foot of horizontal
run). Example 10 ft of horizontal would require a rise of 2.5”.
NOTE: ALLOWING THE VENT PIPE TO SLOPE DOWN TOWARDS THE VENTTERMINATION COULD CAUSE POOR COMBUSTION AND/OR HIGH TEMPERTURES
THAT MAY PRESENT A FIRE HAZARD. Mark a 10” x 10” square around the center mark(inside dimensions).
Cut and frame the exterior wall to accept the wall penetration heat shield. Install thepenetration shield using wood screws. If the wall being penetrated is constructed of noncombustible material a 7” hole sufficient for the vent pipe, is acceptable.
Caution: When installing the termination on to vinyl siding, a vinyl siding kit must be
used. This prevents the termination from being recessed into the siding.
When the termination is to be attached to vinyl siding apply a bead of non-hardening mastic
around the outside edge to form a seal between the standoff and the termination cap. Attach
the termination cap to the exterior wall inserting four wood screws through the holes in thecorner of the vent termination. Complete the installation by applying a bead of mastic aroundthe outer edge of the vinyl standoff.
With the termination cap installed you can now connect the completed vent assembly bysliding the unit back towards the wall and carefully inserting the pipe into the terminal. Before
the final connection is made slide on the decorative wall thimble. Secure the termination cap by
securing the termination straps to the pipe as close to the exterior wall as possible using sheet
metal screws. Ensure that the straps are hidden by the wall thimble cover. Apply decorative
trim if required.

Page 21

INSTALLATION INSTRUCTIONS Cont...
Vertical Installations
Always maintain the 1” clearance around the vent pipe (vertical), when passing throughceilings, walls, roofs, enclosures, attic rafters or any combustible surfaces.
DO NOT PACK AIR SPACES WITH INSULATION.
Refer to the vent chart for maximum allowable vertical and horizontal installations.
When planning your installation determine if ceiling joists, roof rafters or other framing will
obstruct the vent system. You may have to use 45° elbows to navigate around any obstacles.
When passing through a flat ceiling install a Box/Wall thimble. Cut a 10” square hole and frameas shown in the diagram opposite.
Ensure all pipe sections are fully twist locked.

NOTE: ALWAYS CHECK YOUR LOCAL CODES BEFORE INSTALLING VENTING.
NECESSARY CLEARANCES AND REQUIRMENTS MAY VARY FROM STATE TO STATE(PROVINCE TO PROVINCE).

THE CALDERA
MAINTENANCE

PLATING:
1. The plating requires little maintenance and needs only to be cleaned with a soft damp cloth. Do not
use any abrasive cleaning materials.
2. Avoid fingerprints on gold. Wipe off fingerprints before firing.
DOOR :
Check the gasket to see that it is still forming a seal. Replace gasket if there is any sign of wear.
VIEWING GLASS REPLACEMENT:This appliance is supplied with high temperature 5mm high temperature ceramic glass that will easily
withstand the heat your unit was designed to produce. In the event the glass breaks, contact your dealeror BLAZE KING to arrange for your glass to be replaced / repaired (see page 12).
IMPORTANT - GLASS CLEANING - WHITE MINERAL DEPOSITSOne of the byproducts of the combustion process in a gas appliance, is a mineral which can show up asa white film on the ceramic glass of the viewing door. The composition of the deposit varies widely fromvarious locations and also from time to time in the same location. You may have the problem for a time
and then not see it for many months when it will reappear in your area. It seems this is associated withthe varying sulfur content of the gas. We have discussed this problem with ceramic glass manufacturers
and they cannot give us a definitive answer to this problem. Dealers have tried various cleaning productswith varying results. The following recommendations will not guarantee results in your particular case.
Ensure the stove is completely cooled before you change the bulb. Make sure switch on theBattery pack / Receiver is in OFF position.
Turning the electric supply off will not prevent unexpected ignition !!
1. Clean the glass regularly as soon as you notice the buildup (white film). If the film is left for a long
period of time build up will bake on. It is then much harder, if not impossible, to remove.
2. NEVER use an abrasive cleaner on the ceramic glass. Any abrasion of the surface has theimmediate effect of lessening the strength of the glass. An emulsion type cleaner is recommended.
3. Use a soft damp cloth to apply the cleaner. Dry the glass with a soft, dry, preferably cotton cloth.
Most paper towels and synthetic materials are abrasive to ceramic glass and should be avoided.
4. Our dealers have had good results from the products listed below. We can not however guarantee
the results of these products.
a) BRASSOb) POLISH PLUS by KEL KEMc) COOK TOP CLEAN CREME by ELCOd) WHITE OFF by RUTLAND
NOTE: This is a problem beyond Blaze King’s control and is
not covered under warranty.

NOTICE: COLD WEATHER OPERATION
When using any gas appliance (LPG or NAT Gas) water is a byproduct of the combustion process.
Under normal conditions this moisture is expelled through the vent into the atmosphere and does notcause any harm. In extreme cold weather the vapor may condense and freeze on any exposed surface
it comes into contact with. This can cause a problem by restricting or blocking the vent, particularly withdirect vent wall terminations as the exhaust is only a few inches away from the outside wall surface.
What happens to the moisture after it leaves the vent cannot be controlled by the manufacturer. To
extend the vent further out from the wall can sometimes but not always be an advantage. Extending thevent out from the wall may present other design problems such as ice falling from the eaves above. It is
the homeowners responsibility to ensure that there is not an excessive build-up of ice on the termination.
CAUTION: WHEN OPERATING YOUR APPLIANCE DURING COLD WEATHER YOU MUSTFREQUENTLY CHECK THE EXHAUST CAP FOR EXCESSIVE ICE BUILD UP.
If the appliance begins to operate abnormally—Poor flame pattern, shutting down, etc…, this could be
an indication of ice build up.

MAINTENANCE

REPLACING HALOGEN LIGHT BULB (OPTIONAL SHROUDS ONLY)

The light is situated at the inside of the shroud. Replace with the light bulb specified in the replacement
parts list on page 49. To replace the light bulb follow these instructions:
Ensure the stove is completely cooled before you change the bulb. Make sure switch on theBattery pack / Receiver is in OFF position.
Turning the electric supply off will not prevent unexpected ignition !!
1. Turn off electric supply
2. Open the right door (arched shroud) or take off shroud (rectangular shroud)
3. Using a screw driver, remove the cover plate (rectangular shroud only)
4. Remove old bulb by pulling straight out, to insert new bulb, push straight in.
