GPG models are available in both natural gas and propane (except for GPG 81 370 model which is
natural only). To order propane, change the "N" to "P" in the model number. Example: GPG 81 140 PEA
Based on 80% thermal efficiency.
NOTE: To compensate for the effects of high altitude areas above 2000 feet, recovery capacities should
be reduced approximately 4% for every 1000 feet above sea level.
Above capacities are based on actual efficiencies obtained in engineering laboratories.
ASME
(ON SELECTED MODELS)
GENERAL
Water heater(s) shall be Model _________________ as manufactured by State Water Heaters or equal. Water heater(s) shall be of glass-lined design and include a
powered gas burner with redundant main gas valves, electronic ignition, automatic pilot gas valves, gas pressure regulator and flame inspection port. Heater(s) shall
have an input rating of _____ and a recovery rating of _____ gph at a temperature rise of 100˚F with a maximum storage capacity of _____. Heater(s) shall be equipped
1
with 1
⁄
˝ NPT water inlet and outlet openings and (1) 4˝ handhole cleanout on Models GPG81-140 thru GPG81-270; (2) 4˝ handholes on ASME models. Heater(s) shall
2
have a minimum working pressure of 160 psi and include a high temperature limit control, dual thermostat for accurate temperature control and factory installed A.G.A.
T & P valve. Heater(s) shall be equipped with multiple anodes for protection, insulated with a vermin-proof glass fiber insulation and meet ASHRAE 90.1b-1990 for
thermal efficiency and standby loss. The outer jacket shall have a baked enamel finish over a bonderized undercoating. All internal surfaces of the heater(s) exposed to
water shall be glass-lined with an alkaline, borosilicate, nickelous oxide composition that has been fused to the steel by firing at a temperature range of 1400˚F to 1600˚F.
Heater(s) tank shall have a 3 year limited warranty against corrosion as outlined in the written warranty.
CONTROLS: GPG81-140 thru GPG81-370
Controls shall include a Fenwal osi to provide direct spark ignition and flame monitoring. A prepurge of 30 seconds minimum shall be provided. A trial for ignition period
of 5 seconds, after which if the flame is not proved or lost during the running cycle, the system will lock out. System shall include automatic gas valve, main gas pressure
regulator, automatic gas shut-off, manual shut-off, and be rated for 14˝ W.C. maximum gas pressure.
