test solution
- Remove blockage. In really cold conditions, ice buildup may occur
on the terminal and should be removed as required. (To minimize this
from reoccuring, the vent lengths that pass through unheated spaces
(attics, garages, crawl spaces) should be wrapped with an insulated
mylar sleeve).
- Refer to "venting" section to ensure correct installation.
- Check pressure readings:
Inlet pressure can be checked by turning screw (A) counter-clock-
wise 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 fi rmly to reseal. DO NOT OVER TORQUE.
Leak test with a soap and water solution.
