It only requires connection of 115V electrical supply, minor gas train piping, connection to gas service, and operating controls. All Power Flame burners are operationally fire tested at the factory. CAPACITIES & SPECIFICATIONS Burner Number X4-400 X4-700 X4M-400 X4M-700 Natural/LP Gas Flow x 1,000 BTU/HR... - Page 6 If the burner is to be mounted in an existing boiler or furnace, ensure that all fireside surfaces are clean and in good condition. All doors, cleanouts, cracks or other openings allowing excess air into the combustion chamber should be tightly sealed, whether the burner is to be fired under positive or negative combustion chamber conditions.

NOTE: Serious Damage To The Burner May Result If The Blast Tube Is Extended Into The Combustion Chamber. Secure the burner to the heat exchanger or boiler, using the burner-mounting flange. The burner- mounting flange must be secured to the blast tube at the selected location for proper insertion into the end or front wall of the fired unit. -

Install vent lines from main gas regulator (if used) and diaphragm gas valve where applicable. Vent lines should be run to the outside of the building, terminating clear of windows or fresh air intakes. Outside termination of vent should have a screen to prevent insects from building nests in vent pipe. - Page 9 Figure 4 Location of Side Orifice Figure 5 Typical Wiring Diagram for S8680J with Proved Pilot Ignition...

Figure 5A Typical Wiring Diagram for S89F with Direct Spark Ignition WIRING Refer to wiring diagram shipped with burner and typical wiring diagrams Figures 5 and 5A. The two power leads (black and white) are located inside the burner panel. Electrical installation must be made in accordance with the NEC NFPA 70 or Canadian Electrical Code, Part 1 and applicable local codes. - Page 11 Install stack thermometer and Flue Gas Analyzer sample line into breeching and connect the draft gauge to combustion chamber test point. Connect a microammeter to the Primary Safety Control as directed in the PSG control manufacturer’s instruction bulletin to determine flame detection system values. The meter is normally connected in series with the (SENSE) terminal on the S8600 or S89F series control.
- Page 12 Figure 6A Detail Pilot Assembly Frequently the cause for pilot problems relates to gas pressures that are too high and/or air dampers that are closed too far. Both conditions can cause a fuel rich mixture in the pilot chamber which can substantially delay or totally prevent pilot ignition. 7.11 With the leak gas cock closed and pilot gas cock open (if provided);...
- Page 13 Select and install the main orifice that corresponds to the desired firing rate. Make certain that the airflow setting provides the correct CO or O levels and other combustion values at the proper firing input rates. See Section 8 and Table 3 for firing rate information. Generally accepted values for natural gas are 8½...

In the event of extended shutdown, the main power should be turned off and the main manual gas shutoff valve should be closed. EMERGENCY SHUTDOWN: WARNING: Should over-heating occur: (1) shut off the manual gas valve to the appliance, (2) do not shut off the control switch to the feed water pump or blower. An additional source of information relative to trouble shooting can be found in the Flame Safeguard Control Manual supplied with the burner. -
Page 19: Sequence Of Operation For X4M Burners
11. SEQUENCE OF OPERATION FOR X4M BURNER 11.1 Refer to typical wiring diagram for X4M burner (Figure 11A). Upon a call for heat, the blower motor starts, closing the combustion air switch. Power is supplied to the 24-vac transformer. Initially power to the actuator is held out through one set of normally open contacts on the 24-vac relay. -
