Indirect Water Heater System
General
All gas water heaters are certified at 300 PSI test pressure (2068 kPa) and 150 PSI working pressure (1034 kPa). All potable water and electrical
connections are 3⁄4” NPT (19mm) on 11” (279mm) centers. All models design certified by CSA International (formerly AGA/CGA), ANSI Z-21.10.1 and 10.3
and peak performance rated.
Dimensions and specifications subject to change without notice in accordance with our policy of continuous product improvement.
Suitable for Water (Potable) Heating and Space Heating.
Toxic chemicals, such as those used for boiler treatment, shall NEVER be introduced into the potable side of this system. The potable side may NEVER be
connected to any existing heating system or component(s) previously used with a non-potable water heating appliance.
Propane models feature a Titanium Stainless Steel propane burner. For Propane (LP) models change suffix “BN” to “SX”.
*Based on manufacturers rated recovery efficiency.
