shutoff valves (located at the end of the supplied gas train) from the gas and propane supply systems during any pressure testing of the system at pressures in ex- cess of 1/2 psig (14 inches W.C.).

During any pressure testing of the gas supply piping system at pressures equal to or less than 1/2 psig (14 inches W.C.), the boiler should be isolated from the gas supply piping system by closing both manual shutoff valves.

Some leak test solutions, including soap and water, may cause corrosion. These solutions should be rinsed off with water after testing.

Installation

4.3PRE-START CHECK LIST

Before firing the boiler make sure the following items have been completed.

1.Flue gas from the boiler is properly vented.

2.Gas connections have been made and the gas lines purged of air.

3.Water connections are complete, and the boiler and system have been filled and purged of air.

4.The boiler is connected to a 120 volt power source with a lockable disconnect (customer supplied) having adequate overload protection.

5.Combustion air openings are not obstructed in any way and have adequate capacity.

6.The boiler is placed the proper distance from any combustible walls, in accordance with the "Clear- ances" section of the “Installation and Owner’s Manual,” page 3.

7.Relief valves have been piped to floor drains.

4.4PRE-START SAFETY CHECKS AND

ADJUSTMENTS

Before placing the boiler in operation, perform all the following safety checks and adjustments. This work must be performed by qualified service personnel.

Gas vents to outdoor air must be provided for the pressure regulators and gas pressure switches. If ap- proved by authorities having jurisdiction, vents may be manifolded in accordance with accepted engineer- ing practices to minimize backpressure.

The pilot regulator is equipped with a vent limiting device and does not require external venting!

If equipped for I.R.I. (Industrial Risk Insurers) the normally open vent valve must be vented independ- ently from other vented devices, as shown above.

Warning! High voltage! Shock hazard. Properly lock- out/tagout the electrical service and all other energy sources before working on or near the machine.

For testing control circuits only, the service power shutoff switch (located inside the auxiliary panel at the rear of the boiler) may be used to de-energize the sys- tem in lieu of normal lockout/tagout procedures. Use extreme caution when using this alternative.
