Install boiler — packaged boilers only
Place boiler
1. Remove circulator strapped to pallet.
Circulator will be damaged if not removed before
boiler is lifted from pallet.
2. Remove boiler from pallet.
Do not drop boiler or bump jacket on floor or
pallet. Damage to boiler can result.
Smaller sized boilers may be top heavy. Use caution
when handling to avoid minor personal injury or
property damage.
3. Boiler is shipped for back flue outlet. To change to top flue
outlet (see Figure 3, page 11):
a. Remove jacket cap on top of boiler.
b. Loosen two screws holding flue cap strap to collector
hood. Remove strap and flue cap from opening. Re-
tighten screws.
c. Check rope placement inside flue cap.
(Read
under step #6).
d. Loosen two screws on back flue outlet. Set flue cap on
outlet. Install strap by engaging slots in screws. Tighten
screws. Make sure cap is securely installed.
e. Snap jacket cap in back outlet opening.
Jacket cap must be in place on boiler to avoid re-
quiring an 18” minimum clearance from back of
boiler to combustible material.
4. Check level. Shim legs, if needed.
5. Check for secure placement of insulation on target wall,
chamber floor and burner door.
6. Visually check:
a. Flue collector hood seal.
b. Burner mounting door seal.
Obtain gas-tight seal to prevent possible flue gas
leakage and carbon monoxide emissions, which
can lead to severe personal injury or death.
Perform hydrostatic pressure test
1. Remove relief valve installed in boiler.
2. Install air vent in “N” tapping on top boiler.
3. Plug supply and return tappings.
4. Drain valve is already factory-installed.
5. Fill boiler. Vent all air. Pressure test boiler at 1½ times work-
ing pressure.
Do not leave boiler unattended. Cold water fill can
expand and damage cast iron, resulting in severe
personal injury, death or substantial property dam-
age.
6. Check for maintained gauge pressure for more than 10 min-
utes. Visually check for leaks if gauge pressure drops.
7. Drain boiler. Repair leaks if found.
Do not use petroleum-based sealing compounds
to repair leaks. Damage to system components can
result, causing property damage.
8. Retest boiler after repairing leaks.
9. Remove air vent and plugs. Reinstall relief valve.
