2a Prepare boiler — placement & setup

Place boiler/crate near position

1.Leave boiler in crate and on pallet until installation site is ready.

2.Move entire crate and pallet next to selected location.

3.Remove crate.

4.Remove boiler from pallet.

Do not drop boiler or bump jacket on floor or pallet. Damage to boiler can result.

a.Tilt left side of boiler up and place a board under left legs.

b.Tilt boiler the other way and place a board under right legs.

c.Slide boiler backward off pallet and into position.

5.Check level.

a.Shim legs, if necessary.

b.Do not alter legs.

Inspect orifices and burners

1.Remove front jacket door. Remove inlet air box top panel (see Figure 27, item 13, page 54).

2.Check for correctly-sized manifold orifices. See Table 2 for sizing. (The orifice size is stamped on the orifice spud barrel.)

Correctly-sized manifold orifices must be used. Failure to do so will result in severe personal injury,

death or substantial property damage.

3. Reinstall inlet air box top panel.

Inlet air box top panel must be in position during boiler operation. Failure to do so could result in severe personal injury, death or substantial property damage.

Orifice replacement procedure

(when required)

1.Remove the screws securing the inlet air box top panel.

2.Remove inlet air box top panel and inspect the fiber gasket. Verify the gasket is in good condition and can seal around the complete perimeter of the air box. Replace the gasket if necessary.

3.Using a 7/16" open-end wrench, remove the burner orifices from the manifold.

4.Apply a small amount of pipe dope to each of the new orifices and install in the manifold using a 7/16" open-end wrench. Make sure the orifices are aligned correctly, not cross-threaded in the manifold tappings.

Use only pipe dope compatible with propane gas, even if boiler is to be operated on natural gas. Failure to comply could result in severe personal injury, death or substantial property damage.

5.Carefully replace the inlet air box top panel, making sure the gasket is in place will seal all around the perimeter.

6.Follow the check-out procedure, section 8 page 30, to assure the boiler is now operating properly after orifices are replaced.
