11.3 Check Installation
After Startup
□ With the unit in operation, measure valve outlet gas
pressure. See information and instructions in Paragraph
7.1.3. If operated at high altitude, be sure to adjust outlet
gas pressure for altitude.
□ Turn the unit off and on, pausing two minutes between each
cycle. Observe for smooth ignition.
□ Place the packet of information containing the Limited
Warranty, this booklet, and any control or optional
information in an accessible location near the heater.
DANGER:
The gas burner in this gas-red equipment is designed and equipped to provide safe
controlled 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-red gas burning
equipment requires a properly operating vent system that vents all ue products to
the outside atmosphere. FAILURE TO PROVIDE PROPER VENTING WILL RESULT
IN A HEALTH HAZARD WHICH COULD CAUSE SERIOUS PERSONAL INJURY OR
DEATH.
Always comply with the combustion air requirements in the installation codes.
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. MAINTAIN THE VENT/COMBUSTION AIR
SYSTEM IN STRUCTURALLY SOUND AND PROPER OPERATING CONDITION.
12.0 Maintenance
and Service
WARNING: If you turn
off the power supply,
turn off the gas. See
Hazard Levels, page 2.
The material contained in the MAINTENANCE AND SERVICE Section of this man-
ual is designed to aid a qualied service person in maintaining and servicing this
equipment. This heater will operate with a minimum of maintenance. To ensure
long life and satisfactory performance, a heater that is operated under normal con-
ditions should be inspected and cleaned at the start of each heating season. If the
heater is operating in an area where an unusual amount of dust or soot or other
impurities are present in the air, more frequent maintenance is recommended.
When any service is completed, be careful to reassemble correctly to ensure that
no unsafe conditions are created. When re-lighting, always follow the lighting
instructions on the heater.
12.1 Maintenance
Schedule
The following procedures should be carried out at least annually (See FIGURE 28,
page 39, and Paragraphs 12.2.1 - 12.2.16.):
• Clean all dirt, lint, and grease from the combustion air opening and
venter assembly.
• Clean all dirt, lint, and grease from the fan blade, fan guard, and
motor.
• Clean the condensate traps.
• Check the heat exchanger both internally and externally.
• Check the burner for scale, dust, or lint accumulation. Clean if
needed.
• Check gas valve to ensure that gas ow is being shutoff completely.
