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 2):
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 below).
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 requiring
an 18” minimum clearance from back or
top 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 working pressure.
Do not leave boiler unattended.
Cold water fill can expand and
damage cast iron, resulting in severe personal
injury, death or substantial property damage.
6. Check for maintained gauge pressure for more
than 10 minutes. 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.
