[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS:

A. Heater Requirements: The oil‑fired furnace shall conform to Mil.
Spec. 17104 and shall be of the \[upflow,\] \[high‑boy\] type. The
furnace shall be suitable for burning light oil \[Grade 2\]. Capacity
shall be not less than \[\_\_\_\_\_\_\] BTUs per hour output supplying
approximately \[2000\] cfm at \[0.5\] inches w.g. external static
pressure. Fan motor shall be \[3/4\] hp, \[60\] Hz, \[1\] phase. The
furnace shall be suitable for the type of service required and shall fit
the space provided as indicated on the drawings, after adequate room has
been provided for servicing and maintenance.

B. Burner:

1\. Oil burner shall be high pressure atomizing type, rubber‑mounted,
with adjustable combustion air blower, fuel pump, hinged flame
inspection port, cadmium sulphide flame sensor, electrodes, ignition
transformer, and oil nozzle.

2\. Oil burner safety controls shall be thermostat energized burner
motor and electric ignition. Time delay relay limits time for
establishment of main flame. Flame sensor monitors flame continuously
during burner operation and stops burner on flame failure with manual
reset necessary. Solenoid‑operated oil‑delay valve opens after burner
motor is energized and closes instantly when burner motor is
de‑energized.

C. Burner Operation Controls:

1\. Provide low voltage, single stage (heating only), adjustable room
thermostat, to control burner operation to maintain room temperature
settings. Thermostat to be mounted five feet above floor on wall as
shown on the drawings. Thermostat to have \[40 degrees F to 90 degrees
F\] range, with subbase and locking cover. Switching system shall be
\"HEAT‑OFF‑FAN\".

2\. Provide high limit control, with fixed stop at maximum permissible
setting, to de‑energize burner on excessive bonnet temperature and
energize burner when temperature drops to lower safe value.

3\. Provide controls for supply fan in accordance with bonnet
temperatures, independent of burner controls. Include manual switch for
continuous fan operation.

D. Cabinet:

1\. Constructed of heavy‑gauge, cold‑rolled steel.

2\. ab Foil‑covered fiberglass insulation on back, sides, and vestibule
panels.

3\. Return air entry possible on either side of cabinet.

4\. Include a matching return air cabinet as shown on drawing.

E. Heat Exchanger:

C. Flue Connections: Connect the furnace flue pipe \[to the existing
flue stack\] \[with standard flue connections\], and draft regulator
according to NFPA 211.

D. Air Filter: Provide air filters for furnace. Do not operate fans
until filters are installed. After completion of tests, and before
system is accepted by the Contracting Officer, the Contractor shall
furnish and install a new set of filters.

E. Fuel Connections: Connect new furnace burner with \[existing\]
\[new\] oil piping. Make necessary changes to piping as required in
