•Hot water pipes must be at least ½" from combustible material.

Residential garage installation

Install boiler so burners are at least 18 inches above the floor.

Boiler foundation

Never install boiler on combustible flooring or carpeting, even if a concrete or aerated foundation is used. Severe personal injury, death or substantial property damage can result.

1.See Figure 1. A level concrete or solid brick pad is required if:

a)There is a possibility of the floor becoming flooded.

b)Non-level conditions exist.

2.An aerated boiler foundation is recommended if any of the following conditions exist:

a)Electrical wiring or telephone cables buried in the concrete floor of the boiler room.

b)Concrete floor is "green."

c)There is a history of the floor becoming flooded.

d)Water is channeled under the concrete.

Placing the boiler

Block assembly is extremely heavy. Handle with caution to avoid personal injury.

Where the EGH block assembly is taken apart for handling:

1.Put a support under center of block. Support must be within 1/2 inch of block bottom.

2.Remove short center draw rods.

3.Tip half blocks on end as shown in Figure 2. Save elastomer sealing rings and cope seal between sections.

4.After moving half-blocks into desired location, clean port surfaces with clean, dry rag. Do not use oil. Place sealing rings in recessed ports. Place cope seal in section grooves.

5.Re-assemble block in reverse order. When drawing sections together, use 45 ( ± 5) ft-lbs torque.

Installation of optional indirect water heater

For a boiler ordered with internal type indirect water heater, remove heater opening cover plate (water boilers - round plate on left side; steam boilers - rectangular plate on front).

Install heater(s) as shown on pages 13. Do not over tighten studs and nuts - damage to the gasket can occur..
