WARNING Failure to apply pipe dope as detailed above can result in severe personal injury, death or substantial property damage. WARNING Use a two-wrench method of tightening gas piping near the unit and its gas valve. Use one wrench to prevent the gas valve line connection from turning and the second to tighten adjacent piping. Failure to support the gas valve connection piping could damage the valve and the gas line components. Fig. 15: Recommended Gas Supply Piping 28 Fuel Piping Pipe Sizing - Natural Gas 1. Refer to Table 1 for pipe length and diameter requirements. Based on rated ELITE input (divide by 1,000 to obtain cubic feet per hour). -Table 1 is based on Natural Gas with a specific gravity of 0.60 and a pressure drop through the gas piping of 0.30”w.c.. - For additional gas piping sizing information, refer to ANSI Z223.1. For Canadian installations refer to B149.1 or B149.2. Natural Gas Supply Pressure Requirements 1. Pressure required at the gas valve inlet supply pressure port: -Maximum 13”w.c. at flow or no flow conditions to the burner. -Minimum 5”w.c. during flow conditions to the burner. Must be verified during start up. 2. Install 100% lockup gas pressure regulator in the gas supply line if inlet pressure can exceed 13”w.c at any time. Adjust the lockup pressure regulator for 13”w.c maximum. Pipe Sizing - Propane Gas 1. Contact the local propane gas supplier for recommended sizing of piping, tanks and 100% lockup gas regulator. Propane Gas Supply Pressure Requirements 1. Adjust the propane supply regulator provided by the gas supplier for 13”w.c. maximum pressure 2. Pressure required at the gas valve inlet supply pressure port: -Maximum 13”w.c. at flow or no flow conditions to the burner -Minimum 5”w.c. during flow conditions to the burner. Must be verified during start up.

For installations in Canada, CSA B139, Installation of Oil-Burning Equipment If the fuel tank is installed or any part of the fuel tank is above the level of the burner, an anti-siphon device must be installed to prevent the spillage of oil in the event of an oil line break. Support oil line as required by local codes. All tank connections should be made using swing joints or copper tubing to prevent possible line breakage in the event of tank settlement. When using swing joints ensure they are made to tighten as the tank settles. All thread connections should be made with a non-hardening pipe joint compound. WARNING Do not use Teflon tape to seal any oil connections. Teflon tape can cause oil valves to fail, creating potential hazards. Do not use compression type fittings at the burner all fittings should be flare type. 30 Internal Wiring SECTION VIII - Internal Wiring WARNING ELECTRICAL SHOCK HAZARD. For your safety, disconnect electrical power supply to the unit before servicing or making any electrical connections to avoid possible electric shock hazard. Failure to do so can cause severe personal injury or death. NOTICE All electrical contacts shown in Figures 15 & 16 pages 31 & 32 do not have electrical power applied. Shown as “offshelf” condition. General Requirements -Wiring must be N.E.C Class 1. -If original wiring as supplied with the unit must be replaced, use only type 90.C wire or equivalent. -The ELITE must be electrically grounded as required by National Electrical Code ANSI/NFPA 70 - latest edition. 120 VAC On-Off Switch Manual Reset Limit EquipmentGround Circulator Burner Control FactoryJumper FactoryJumper LWCO W W BL BL BL BL BL OR Y Y Y V B BB Brr BB B B B B H N H 2 1 3 4 5 7 9 12 1212 10 13 11 R2A R2B R1A 120V 24V Room T-Stat Snap-Set SecondaryT-Stat PrimaryT-Stat Fig. 15: ELITE Factory Internal Wiring Wire Color Code Auto Reset Limit V V VT T P P 6 14 R1 R2 31 Internal Wiring Wire Color Code Room T-Stat Snap-Set LWCO Burner Circulator Relay R2 Relay R1 Transformer Secondary T-Stat Manual Reset Safety Limit Auto Reset Safety Limit Primary T-Stat On-Off Switch C 2 1 Y O BL G T T TT B BL BL BL BL B B B B R V W G W Y Y Y YPP V V V B C B B B B BL B B 1 1 3 64 1 3 64 14 13 12 11 10 9 8 7 6 5 4 3 2 1 G G G B G G 120V Incoming Supply WiringN H W G C 1 2 C 1 2 120V Field Wiring (by others) 120V Factory Wiring 24V Factory Wiring Fig. 16: Factory Wiring Schematic 32 External Wiring SECTION IX - External Wiring Installation Compliance All field wiring m...
