exhausts, so they shall operate at maximum speed. Do not operate a summer
exhaust fan. Close fireplace dampers.
4. Light the heater following the lighting instructions. Adjust the thermostat for
continued operation. Verify that combustion products are venting properly. After
determining that the heater vents properly, return doors, windows, exhaust
fans, and fireplace dampers to their previous conditions. If improper venting is
observed, the venting system must be corrected.
 With the unit in operation, measure manifold gas pressure. Manifold pressure for
natural gas should be 3.5" w.c. and 10" w.c. for propane. See Paragraph 6.1.
 Turn the unit off and on, pausing two minutes between each cycle. Observe for
smooth ignition.
 If equipped with a dirty filter switch, set the switch (See Paragraph 7.4).
 Place the "Owner's Envelope" containing the Limited Warranty, this booklet, the
operation/maintenance/service manual, and any control or optional information in
an accessible location near the heater. Follow the instructions on the envelope.
 IMPORTANT: After at least 8 hours but no longer than a week of operation,
recheck the blower wheel, all set screws, blower pulley, motor pulley, and belt ten-
sion. Make any required adjustments.
DANGER
The gas burner in this gas-fired equipment is designed and equipped to provide safe,
complete combustion. However, if the installation does not permit the burner to receive
the proper supply of combustion air, complete combustion may not occur. The result is
incomplete combustion which produces carbon monoxide, a poisonous gas that can cause
death. Safe operation of indirect-fired gas burning equipment requires a properly operating
vent system which vents all flue products to the outside atmosphere. FAILURE TO PROVIDE
PROPER VENTING WILL RESULT IN A HEALTH HAZARD WHICH COULD CAUSE SERIOUS
PERSONAL INJURY OR DEATH.
If installed as a separated-combustion unit, install either the horizontal or vertical combustion
air/vent system illustrated in Paragraph 6.2.1 using the concentric adapter supplied. Always
comply with the combustion air requirements in the installation codes and instructions.
Combustion air at the burner should be regulated only by manufacturer-provided equipment.
NEVER RESTRICT OR OTHERWISE ALTER THE SUPPLY OF COMBUSTION AIR TO ANY
HEATER. CHECK THE VENT SYSTEM FOR SOUNDNESS AND FUNCTION; MAINTAIN IT IN
PROPER OPERATING CONDITION.
