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
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. Model UDAP units installed in a
conned 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.
