The appliance can be installed in the following constructions:
2.1
Solid fuel (Non-combustible) fireplaces
As supplied, this appliance can be installed as an inset in an existing solid fuel type fireplace with a chimney and 3" dia liner (seefig.1a).
The fireplace must be built in accordance with the national, state provincial or territorial building code recognized by theauthority having jurisdiction, or in the absence of such a code, in accordance with the National Building Code of Canada or the
National Fire Protection Association code in the USA The size of the fireplace recess must be sufficient to accommodate theappliance case as shown in fig.1a.
The chimney must be swept and both chimney and fireplace checked for soundness before installation of the appliance. The liner
must be a type approved by the enforcing authority and installed in accordance with the manufacturer's instructions.
The appliance must be installed on a non-combustible floor. The floor must be sufficiently flat and level to support the appliancesatisfactorily. Some fireplace constructions have a well in the floor at the back that may need to be filled in. In the USA it ismandatory that a hard surfaced non-combustible hearth area must be maintained at least 16" in front of the fireplace. This may befinished in brick, ceramic tile, marble, etc. Raising the hearth slightly will help to minimize dust and lint accumulation under theunit.
In Canada, though not mandatory, we recommend that carpet, soft vinyl or other combustible floor coverings are kept at least 16”
from the front of the furnace since these types of materials may be affected by the high radiant heat output from this appliance.
The minimum clearances from any combustible constructions at the front of the appliance are shown in fig.1b. These front
clearances apply for all installations.
2.2
Enclosures constructed with combustible materials#770ZCK Zero clearance kit must be installed where the furnace is intended to be in an enclosure made with wood studding orother combustible materials.
The enclosure framing requirements are shown in figures 1c through 1f.
Note that in Canada, though not mandatory, we recommend that carpet, soft vinyl or other combustible floor coverings are kept
at least 16” from the front of the furnace since these types of materials may be affected by the high radiant heat output from thisappliance.

during any pressure testing of the gas supply piping system at test pressuresequal to or less than 1/2 psig (3.5kPa).
7.9.3. Burner operation check
Check ignition, pilot stability, burner selection control, burner flames and theFig. 33 Bottom Louver Attachment (Standard fascia)
full range of the thermostat using the rotary switch inside the appliance andall other controls (appliance rocker switch, remote hand unit). See owner’s
lighting instructions further on in this manual for full details.
7.9.4. Aeration adjustment
On natural gas appliances (Model 737XN) both front and rear burners are equipped withadjustable shutters to control primary aeration. The air holes are at the right side of the front andrear burner rails - See fig 32. The shutters can slide to the right to reduce the air supply or to theleft to increase it.
The appliance is supplied with the shutters set to suit the vast majority of installations. No
adjustment should usually be necessary. However, in certain installations (e.g. Low Btu value gas,high altitude) it may be necessary to adjust the shutter position of one or both of the burners to
obtain the optimal visual effect.
Aeration is not adjustable on Propane appliances (Model #737XP)

7.11. Venting check
A check for correct venting of combustion products must be made before the installed appliance is left with the customer.
7.11.1 Ignite the pilot. Turn the burner selector to both burners on. Turn themain control valve to the fully on position and the thermostat to its
highest setting.
7.11.2 Leave for 15 minutes.
7.11.3 Using a piece of cardboard from the packaging or similar material, cut
a section approximately 12” square.
7.11.4 Light a long match. Hold the piece of cardboard immediately below
the slots at top of the front unit and near the center. This will preventthe convection air from interfering with the test. Insert the match into
one of the slots near the center (Fig. 37). The installation is satisfactory
if the smoke is drawn into the appliance.
Fig. 37 Venting check7.11.5 If the smoke spills out of the slots, inspect the sealing at the ventconnection unit.
7.11.6 If the sealing is satisfactory but the smoke still spills out, turn the appliance off and check the vent system thoroughly for cause oflack of pull. If necessary get expert advice. Do not let the appliance be operated without correct venting.

7.12. Final check7.12.1
7.12.27.12.37.12.4

Recheck all gas controls and the thermostat operation.
Instruct the owner how to operate the appliance.
Point out the location of the supply shut-off valve and how to close it.
Recommend that the appliance should be inspected and, if necessary serviced at least once a year.

188. OPERATING PROCEDURE
For full lighting instructions see next page.
The operating instructions are also on a chain at bottom of the appliance.

8.1. General operating notes
8.1.1 For your safety this appliance is fitted with a flame supervision device which will shut off the gas supply if, for any reason, thepilot flames go out. This device incorporates a fixed probe which senses the heat from the pilot flame. If the probe is cool, thedevice will prevent any gas flow unless the gas control knob is kept pushed in at the pilot position.
8.1.2 Burner selection
The appliance has a burner selector control which allows you a choice of either both burners alight or only the rear burner.
8.1.3 The Valor Temperature Control System
A built-in modulating thermostatic control automatically adjusts flame height up or down to maintain room comfort. This
provides steady heat output rather than on/off heating like many thermostat systems commonly used. This results in superiorroom comfort and better heater efficiency*.
*If, however, even when the flames are fully lowered the temperature cannot be reduced down to your chosen heat setting, thesystem will shut the main burner off leaving the pilot only on until the temperature has dropped to an acceptable level. The
burner will then relight. If the room is left empty while the heater has shut down to pilot only alight, be aware that the flames will
relight if the temperature in the room drops sufficiently – keep combustible objects away from the fire.
8.1.4 When first turned on, the decorative flames will appear predominantly blue. After approximately 15 minutes the flames willturn yellow.
8.1.5 After approximately three hours use at a high control setting the fuel pieces will show areas of charcoal gray color as would real
burning logs.

8.2. Cleaning
8.2.1 Only clean when the appliance is cold.
8.2.2 Normally, the appliance should only need dusting. Any stains on the ceramic glass window can be removed with a nonabrasive cleaner. Never use abrasive cleaners on the glass. The stain should not be allowed to build-up, as removal
may then be difficult.
8.2.3 On first using the fire, a white deposit may form around the upper outlet grille. This can be cleaned off with a damp cloth andsoapy water. After the fire has been run on ‘high’ setting for a number of hours, the deposit will not reappear.
8.2.4 Dust, etc. can be brushed from the ceramic logs, base bricks and side walls after detaching the inner front unit and window. If
you are removing the ceramic parts, we suggest that they are removed in the reverse order to that shown in the fuel bed
assembly section of this manual (Section 7.8).
Dust etc. can also be removed from the burners using a soft brush after removing the logs. When cleaning the burners also checkthe aeration holes (see fig.32) and brush clean if necessary. Make sure that no particles are brushed into the burner tubes.
8.2.5 Coloring of the interior of the metal fire box with use is normal. Do not try to remove the color with abrasive materials.

8.3. Checks
8.3.1

8.3.2
8.3.3
8.3.4

A periodic check of the pilot and burner flames should be made.
Check after the fire has been on for at least 30 minutes. The pilot
flame must cover the tip of the thermocouple probe. The mainburner flame pattern will vary from appliance to appliance dependingon the type of installation and climatic conditions. See figures 39 &40.
The appliance area must always be kept clear and free fromcombustible materials, gasoline and other flammable vapors andliquids.
Keep the area in front at the bottom of the appliance clear.
Obstructions will impede the flow of air to the appliance and cause
incorrect combustion.
The flow of combustion and ventilation air must not be obstructed.
The venting system should be examined by a qualified agency
regularly. We suggest annually.
