DANGER
The gas burner in this gas-fired 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-fired gas burning
equipment requires a properly operating vent system that 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.
Always comply with the combustion air requirements in the installation codes
and in Paragraph 6.2. 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. Standard Power Vent models
units installed in a confined space must be supplied with air for combustion as
required by Code and in Paragraph 6.2 of this heater installation manual. MAINTAIN
THE VENT OR VENT/COMBUSTION AIR SYSTEM IN STRUCTURALLY SOUND AND
PROPER OPERATING CONDITION.
 With the unit in operation, measure valve outlet gas pressure. If operated at high
altitude, adjust outlet gas pressure for altitude.
See information and instructions in Paragraph 6.1.
 Turn the unit off and on, pausing two minutes between each cycle. Observe for
smooth ignition.
 Place the "Literature Bag" containing the Limited Warranty, this booklet, the venting
manual, and any control or optional information in an accessible location near the
heater.
10.0 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 manual
is designed to aid a qualified service person in maintaining and servicing this equip-
ment. This heater will operate with a minimum of maintenance. To ensure long life and
satisfactory performance, a heater that is operated under normal conditions 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.
Inspect the burner/control compartment annually to determine if cleaning is necessary.
