Recommended Specifications:

Hot Water Supply Heater(s) shall be model ________________, manufactured by RHEEM-RUUD,

having gas input of __________ Btu/hr. and recovery rate of _____________ GPH at a 100°F tempera-

ture rise when tested and certified at ____________ thermal efficiency. Water heaters(s) shall have the

CSA seal of certification and supplied with a factory installed 125 PSIG ASME pressure relief valve. Water heater(s) shall meet or exceed the thermal efficiency requirements of ASHRAE. Water heater(s) shall be ASME inspected and stamped for 160 PSI working pressure complete with manufacturer’s data report. Water tube heat exchanger shall be constructed of straight integral copper fin tubes with fins spaced at seven fins per inch. Tube sheets shall be ASME fire box steel. Headers shall be of glasslined cast iron and joined to the copper tubes and tube sheets by means of silicone “O” rings to form a posi- tive seal between the copper tubes and the headers to 1200 PSI hydrostatic pressure. Headers shall be secured to the tube sheets by properly spaced bolts and flange nuts. Heat exchanger shall be readily cleanable from either the right or left sides (or rear) of the water heater by removing header(s), and on the right side, cleanable without removing external piping. Heat exchanger to be explosion proof on the water side. Waterways to be 100% copper and glasslined cast iron to prevent galvanic action within the water heater by positively sealing off water contact between ferrous and non-ferrous metals. Pump, flow switch, and energy saving pump control are to be factory supplied and units over 400,000 Btu/Hr. must have electronic intermittent pilot ignition.

Water heater to be equipped with remote bulb electric high limit control adjustable to 200°F. Main electric gas valve to be 24 volt with 110/24 volt transformer. Gas pressure regulator to be factory set at 4" W.C. Flame supervision shall be either 60 second thermopilot or 1-4 second electronic shut down.

Burners to be raised port and die formed from stainless steel alloy, mounted on a removable drawer, capable of quiet ignition and extinction, and equipped with fixed primary air ports.

Models above 330,000 Btu/Hr. shall be CSA design certified for a minimum efficiency of 82% on indoor and outdoor models.

Limited Warranty

All GB models feature a five year limited warranty on the copper heat exchanger and glasslined cast iron header. Please refer to Commercial Warranty Information brochure for complete limited warranty information.
