START-UP AND OPERATING INSTRUCTIONS
WARNING
After placing boiler into operation, the ignition system safety shutoff
device must be tested by the following test method.
1. Reset High Limit Temperature Control to lowest setting.
(See figure 38, page 44).
2. Reset System Controller to maximum setting, causing a call
for heat and allowing unit to run until High Limit Temperature
Control trips.
3. Resetting the High Limit Temperature Control to a higher
setting, unit should run.
4. Reset System Controller and High Limit Temperature Control
to desired temperature. If unit fails to run, see Trouble-Shooting
in this manual.
Before operating the boiler, the entire system must be filled with
water, purged of air and checked for leaks. Do not use Stop Leak
or other boiler compounds. The gas piping should also be leak
tested.
Any safety devices including low water cutoffs used in conjunction
with this boiler should receive periodic (every six months)
inspection to assure proper operation. A low water cutoff device of
the float type should be flushed every six months. All relief valves
should be inspected and manually operated at least twice a year.
