The fully modulating, on-demand, condensing gas fired tankless water heater(s) shall be Rheem models RTGH-C95DVLN,
RTGH-C95DVLP, RTGH-C95XLN, or RTGH-C95XLP, having an input rating of 11,000 Btu/h through 199,000 Btu/h and available
in NG or LP. The heater(s) shall have ¾ in. male NPT water and gas connections. The heater(s) shall have a minimum flow rate
of 0.26 GPM and an activation rate of 0.40 GPM. An integrated condensate neutralizer will be included with every unit. The inlet
gas supply pressures shall be 4.0 in. WC (min.) up to 10.5 in. WC (max) for NG and 8.0 in. WC (min.) up to 13 in. WC (max.) for
LP. The heater(s) shall be factory s upplied with a manual gas shutoff valve, a pressure relief valve, 2 water service valves and a
temperature remote, RTG20006, that can be installed up to 195 ft. from the heater using 18 gauge ( minimum) control wire. The
temperature remote shall provide diagnostic information, fault history, and heater set temperature with a minimum set water
temperature of 85°F and maximum set water temperature of 185°F. The heater(s) shall operate using 120 V / 60 Hz power source.
The heater(s) will incorporate a factory installed power cord (indoor models only).
The indoor heater(s) shall be vented with 2", 3" or 4" diameter PVC schedule 40, CPVC schedule 40, CentroTherm PPs or ABS
(U. S. only) with a length not to exceed 5 ft. (equivalent) for 2", 38 ft. (equivalent) for 3" vent or 94 ft. (equivalent) for 4" vent,
terminating horizontally or vertically. The intake pipe may use material such as PVC, ABS, PP, or aluminum and cannot exceed 5
ft. (equivalent) for 2", 38 ft. (equivalent) for 3" vent or 94 ft. (equivalent) for 4" vent. For single vent applications the heater can use
room make up air. RTGH-C95DVLN or RTGH-CM95DVLN can be common vented with up to 8 units in-line with an 8" diameter
trunk line. The outdoor heater(s) shall be constructed with an integral exhaust vent on the front of the heater.
The water heater(s) shall use a copper, fin tube primary heat exchanger. The secondary heat exchanger shall be constructed from
stainless steel 316L. The heater(s) shall be controlled by an on-board solid-state printed circuit board which uses the following
factory installed components: thermistors to monitor water inlet and outlet temperatures and heat exchanger temperature; a flow
sensor to measure flow rate; flame rods to monitor flame is on or off and if oxygen level is appropriate. The heater shall include in-
line fusing for electrical surge protection, an electronic igniter coil, aluminized stainless steel burners, Guardian OFW overheat film
wrap, heat exchanger thermistor and outlet thermistor to work as high limit switch, modulating gas valve, an ambient thermistor
and freeze protection to -30°F.
The heaters can manifold controls to EZ-Link up to 2 heaters to provide additional capacity. The EZ-Link controls shall be built
onto the on-board solid-state printed circuit board and does not require external controls. The heaters can use a MIC-6 controller,
RTG20213A, to manifold 2-6 heaters or a MIC-185 controller, RTG20126A & RTG20126B, to manifold 2-20 heaters. The EZ-Link,
MIC-6, or MIC-185 controls shall modulate the system for the most efficient performance and rotate the initial heater for balanced
duty/cycle operation. The heater(s) shall be CSA approved for sale in the United States and Canada, ENERGY STAR
®
qualified
with a Thermal Efficiency of 96% for Indoor and 95% for Outdoor units, meets the energy efficiency requirements of the U.S.
Department of Energy and ASHRAE 90.1-2007, and complies with Ultra-Low NOx emissions of 14 ng/J or 20 ppm.
The fully modulating, on-demand, condensing gas fired tankless water heater(s) shall be Rheem models RTGH-CM95DVLN,
RTGH-CM95DVLP, RTGH-CM95XLN, or RTGH-CM95XLP
Same as non-manifold ready (see above) until 4th paragraph
The manifold ready heaters can manifold controls to EZ-link up to 20 heaters to provide additional capacity. Each manifold ready
heater shall include a factory installed control module and the control cable shall be included with the units. The heaters controls
shall modulate the system for the most efficient performance and rotate the initial heater for balanced duty/cycle operation. The
heater(s) shall be CSA approved for sale in the United States and Canada, ENERGY STAR
