18 | Rheem® Commercial Gas Tankless Water Heater Systems
For Rheem® Commercial Tankless Natural Gas Water Heaters Overview Rheem offers a manufacturer tested and UL/ULC listed common venting system providing longer lengths and fewer wall penetrations than single-unit venting. The system is polypropylene stabilized (PPs) material and Intertek certified for UL -1738 and ULC-S6 36 and manufactured by CentroTherm EcoSystems in the USA. Venting pieces are self-locking and sealing and can be pushed together without the use of cement or glue.
The common vent system is CSA certified (ANI Z21.10.3, Gas Water Heaters Standards) for use with up to 10 units of the following Rheem high efficiency, natural gas tankless water heaters; RTGH-C95DVLN and RTGH-CM95DVLN.

In keeping with its policy of continuous progress and product improvement, Rheem reserves the right to make changes without notice.
Water INTEGRATED HOME COMFORTCommercial GasTankless Water Heater Systems
Commercial Tankless SystemThe Commercial Tankless System model # ________________ shall be a factory assembled pre-plumbed system on a frame and include Rheem RTGH-CM95 Condensing Tankless Water Heaters. The system shall include single point connections for incoming water, outgoing water, gas, condensate drainage and electrical.
The system shall include 2.5 inch copper water supply manifolds with 2 foot long 3/4 inch flexible stainless steel water lines to the heaters, a 1-1/2 inch schedule 40 gas supply manifold with 3 foot long 3/4 inch CSST flexible gas lines to the heaters, and isolation valves with 150 psi pressure relief valves for each heater.
The system shall be assembled as a wall hanging, wall mount, or free standing design based on the model number. All configurations will fit through a standard 36" door opening. The frame will be constructed of powder coat painted 16 Gauge steel for wall hanging or 14 Gauge Galvanized Steel for wall mount and free standing
The commercial tankless system shall include factor installed control manifolding for all units and be expandable for up to 20 heaters.
RTGH-CM95 Condensing Tankless Water HeatersThe fully modulating, on-demand, condensing gas fired tankless water heater(s) shall be Rheem models RTGH-CM95DVLN, RTGH-CM95DVLP, RTGH-CM95XLN, or RTGH-CM95XLP, having an input rating of 11,000 BTU/h through 199,900 BTU/h and available in NG or LP. The heater(s) shall have 3/4 inch 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 supplied 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 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 inline 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 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 according to ANSI Z21.10.3 and CSA 4.3 for sale in the United States and Canada, ENERGY STAR® qualified with a minimum 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, and will be certified to NSF 5 standards.
VentingIndoor Independent Venting: 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 and common vent applications the heater can use room make up air.
Indoor Common Venting: RTGH-CM95DVLN shall be common vented with up to 4 units back-to back with a 6" diameter trunk line or up to 8 units back-to back with an 8" or 10" diameter trunk line. The common vent system shall be manufactured from polypropylene solid and be rated to a maximum vent pressure of 20" of water column and UL-1738 & ULC-S636 for use with maximum flue gas temperatures of 230°F (110°C).
Outdoor Venting: The outdoor heater(s) shall be constructed with an integral exhaust vent on the front of the heater.
