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.
Figure 1 Boiler foundation
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..
