K. INITIAL START UP:
This furnace does not have a pilot. It is equipped with a hot surface igniter, which
automatically lights the burner. Do not attempt to light the burner by hand. Check the
following items before the initial start-up.
1. Check all wiring for proper hook up. Tighten any loose connections.
2. Using a soap solution, leak test gas piping connections.
3. Check all tubing connections to the pressure switch, inducer, burner box, and gas
valve and make sure they are connected firmly at all their connection points.
4. Check flue pipe, combustion air inlet, and all joints for tightness and to make sure
there is no blockage.
5. Make sure air filter is in place.
6. Make sure the outside vent and air intakes are installed according to instructions
and are free from blockage.
OPERATING INSTRUCTIONS:
: Turn off power to furnace before it is placed into service. The gas
piping system must have been leak tested by a qualified heating contractor. (See
Section IV, H, of these instructions on the installation of gas piping).
: It may be necessary to purge the air out of the gas line for initial start-
up of the furnace after installation. A qualified heating contractor should do this.
If excessive gas escapes when purging the gas supply at the union, allow the
area to ventilate for at least 15 minutes before attempting to start the furnace.
Propane gas is especially dangerous because the specific gravity of propane gas
allows it to accumulate at floor level at a dangerous concentration.
: Heat exchanger oil will burn off on initial firing creating an unpleasant
odor. To prevent this odor from occurring more than once, it is suggested that:
1. A window(s) be opened.
2. The thermostat be set at highest setting.
3. The furnace remains running at conditions 1&2 for 30 minutes or until odor
has dissipated.
L. ADJUSTMENT OF HEAT INPUT RATE:
The orifices for this furnace were sized: 1) for natural gas having a heating value of
1025 BTU per cubic foot and a specific gravity of .65, or 2) for liquefied propane gas
with a heating value of 2500 BTU per cubic foot and a specific gravity of 1.55. The
rating label inside the furnace vestibule will specify which gas your furnace is orificed
for. If the furnace is installed at an altitude that is more than 2,000 feet above sea level,
