Installation
2.6 — Packing Plastic Refractory Around Oven (If Dry Oven is Supplied)
The area between the outside circumference of the blast tube and existing refractory should be packed with Kaiser
Refractory Mono T-9 Airset or equal within two hours after coating the dry oven with Trowleze. From inside the fur-
nace, ram the plastic refractory from the front to the rear, parallel to the outside surface of the dry oven.
2.7 — Gas Piping
Refer to Figures 1-2,1-3, and 1-4 for typical gas piping schematics.
Gas service and house piping must supply the quantity of gas demanded by the unit at the pressure required at the
burner gas train inlet. All piping must be in strict accordance with applicable codes, ordinances, and regulations of the
supplying utility. In the absence of other codes, piping should be in accordance with the following standards: “National
Fuel Gas Code” NFPA No. 54, ANSI No. Z 223.1 (for Canada, the Canadian Gas Association (CGA) B149 and
Canadian Standards Association (CSA) B140 codes shall prevail).
On-Off operation gas train components are shipped loose. Full modulation gas train components upstream of the
butterfly valve are shipped loose. These components should be mounted by the installer as close to the burner as
practical. Normally, the control train is ordered to suit a particular code or insurance regulation, such as Underwriters
Laboratories Inc., CGA, or Factory Mutual.
Arrange gas piping at the burner so that the burner is accessible for servicing without disassembly.
The gas piping must be internally clean and free of foreign material. Before using in service, a leak test must be
performed.
2.8 — Installation Checklist
All burners are carefully assembled and tested at the factory, but before being placed in service, all connectors should
again be checked for looseness caused during shipment.
Check:
•
Electrical terminals in the control panel and on all electrical components.
•
Pipe fittings, unions and tube connections.
•
Nuts, bolts, screws.
Before connecting electrical current to any component, be sure the supply voltage is the same as that specified on
component nameplates.
Before firing, make sure that the burner mounting flange is properly sealed to the boiler front plate.
It is important that you provide support for the housing when in the open position to prevent damage to the burner and sub-
sequent components.
