Prepare boiler location
Perform hydrostatic pressure test:
See pages 2 and 3 for boiler feature locations.
1. Install air vent in relief valve tapping.
2. Plug supply and return tappings.
3. Install the boiler drain valve shipped with boiler.
4. Fill boiler.
5. Vent all air.
6. Pressure test boiler at 1½ times working pressure.
Do not leave boiler unattended. Cold water fill can ex-
pand and damage cast iron, resulting in severe personal
injury, death or substantial property damage.
7. Check for maintained gauge pressure for at least 10 minutes.
Visually check for leaks if gauge pressure drops.
8. 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.
9. Retest boiler after repairing leaks.
10. Remove air vent and plugs. Reinstall relief valve.
Boiler preparation
Changing door hinge
The boiler is shipped with the burner door hinged on the left side. The
hinge bracket can be relocated to the right side if desired. See Figure 4.
1. Remove jacket front panel.
2. Remove and retain burner door screws and washers used to fasten
the burner door to the front section (one on each side of door).
3. Carefully lift the burner door so the door pins lift out of the hinge
bracket.
4. Set the burner door aside temporarily.
The burner door is heavy. Handle carefully to avoid
potential for personal injury.
Do not damage the burner door insulation when han-
dling.
5. The hinge bracket has keyhole slots. Loosen the two (2) screws
securing the hinge bracket to the front section. Remove the hinge
bracket.
6. Loosen the two (2) screws on the opposite side. Place the hinge
bracket on that side and tighten the two screws to secure the
bracket. Also tighten the two (2) screws on the other side.
7. Carefully lift the burner door and position so the door pins slide
into the hinge bracket holes. The lower pin is longer than the up-
per. So align the lower pin, then the upper.
8. Replace burner door screws and washers used to fasten the burner
door to the front section (one on each side of door).
