Installation (continued)

Figure 3

Pressure test before attaching gas piping or electrical supply.

1.Plug any necessary boiler tappings or openings.

2.Do not use gauge supplied with boiler for pressure testing. Install gauge with appropriate range.

3. Fill boiler with water.Vent all air. Test steam boilers between 45 - 55 psi and water boilers at 1-1/2 times working pressure.

Installation of flue collector hood

(Factory installed on PEG boilers)

Set flue collector hood on boiler as shown in Figure 4. Use boiler cement furnished to provide gas-tight seal.

Failure to maintain gas-tight seal can cause flue gas spillage and carbon monoxide emissions, resulting in severe personal injury or death.

	Do not leave boiler unattended. A cold water fill could expand Figure 4	Flue collector hood
	and cause excessive pressure, resulting in severe personal injury,

	death or substantial property damage.
4. Check for maintained gauge pressure and leaks. Repair if found.
	Leaks must be repaired at once. Failure to do so can cause boiler

	damage, resulting in substantial property damage.
	damage, resulting in substantial property damage.
	Do not use petroleum-based sealing compounds in boiler system.

	Severe damage to boiler will result, causing substantial property

	damage.

5.Drain boiler and repair leaks if found.

6.Retest boiler after repairing leaks.

7.Removeplugsfromanytappings that will beusedforcontrols and accessories. Refer to control tapping table and Figure 3.

8.On initial start-up check for leaks in the system piping. If found, repair at once.

Installation of front and back base panels

See Figure 5 for installation. Fasten front (6 1/8 inch) and back 7 5/16 inch) base panels to sections. Seal with boiler cement along top of insulation panels.

Failure to maintain gas-tight seal can cause flue gas spillage and carbon monoxide emissions, resulting in severe personal injury or death.
