EGH SERIES 5 GAS-FIRED BOILERS — BOILER MANUAL

Placing the boiler

Block assembly is extremely heavy. Handle with

caution to avoid personal injury.

EGH boilers only —

When an EGH block assembly is taken apart for handling:

1. Put a support under center of block. Support must be

within ½ inch of block bottom.

2. Detach seal replacement kit from the draw rod. Remove

short center draw rods.

3. Tip half blocks on end as shown in Figure 4. Save elas-

tomer sealing ring between sections.

4. Remove the exposed silicone from the socket areas

located in the bottom-front and top-rear corners of the

casting. See Figure 4a. Do not remove the rope seal.

5. After moving half-blocks into desired location,

clean port surfaces with clean, dry rag. Do not use

petroleum-based solvents. Place sealing rings in

recessed ports. Place new silicone in the socket area as

seen in Figure 4b. It is critical to place enough silicone

in this area to reseal the castings.

Do not use petroleum-based cleaning or

sealing compounds in boiler system. Severe

damage to system components can result,

causing substantial property damage.

6. Re-assemble block in reverse order. When drawing sec-

tions together, use 45 ( ± 5 ) ft-lbs torque.

been removed.

Place enough silicone in the socket to

make a seal with the mating surface on the

adjacent casting when assembled.
