WARNING
TEST SOLUTION
- Reset by turning power source off then on.
NOTE: If back up batteries are installed, they
must also be removed to re-program.
- 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.
- Refer to "VENTING" section to ensure correct
installation.

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 as described on the chart below. Check
that main burner is operating on 'HI'. Outlet pressure
can be checked the same as above using screw
(B). Gauge should read as described on the chart
below. 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.
