Blockage in vent. - Remove blockage. In really cold conditions, ice buildup
may occur on the terminal and should be removed as
required. To minimize this from happening again, it is
recommended that the vent lengths that pass through
unheated spaces (attics, garages, crawl spaces) be
wrapped with an insulated mylar sleeve. Prevent sleeve
from sagging. Contact your local authorized dealer for
more information.
Incorrect installation. - Refer to “VENTING” section to ensure correct location of
storm collars.
Flames are
consistently
too large or
too small.
Carboning
occurs.
Unit is over-fi red or
underfi red.
- Check pressure readings:
Inlet pressure
can be checked by turning screw (A)
counter-clockwise 2 or 3 turns and then placing pressure
gauge tubing over the test point. Gauge should read
7” (minimum 4.5”) water column for natural gas or 13”
(minimum 11”) water column for propane. Check that
main burner is operating on ‘HI’.
Outlet pressure
can be checked the same as above
using screw (B). Gauge should read 3.5” water column
for natural gas or 10” water column for propane. Check
that main burner is operating on ‘HI’.
AFTER TAKING PRESSURE READINGS, BE SURE
TO TURN SCREWS CLOCKWISE FIRMLY TO
RESEAL. DO NOT OVER TORQUE.
Leak test with a soap and water solution.
