Meets NAECA Requirements
General
All gas water heaters are certified at 300 PSI test pressure (2068 kPa) and 150 PSI working pressure (1034 kPa). All potable water connections are 3/4" NPT
(19mm) on 11" (203mm) centers. All heat exchanger connections are 1" NPT (25mm). All gas connections 1⁄2" (13mm).
All models design certified by CSA International (formerly AGA/CGA), ANSI Z-21.10.3 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 water side. The potable side of this unit may NEVER
be connected to any existing heating system or component(s) previously used with a non-potable water heating appliance. The heat exchanger side of the
unit may be used in space heating applications.
Propane model features a Titanium Stainless Steel propane burner. For propane (LP) models change suffix “BN” to “SX”.
*Based on manufacturers rated recovery efficiency.
*These values were obtained using 180°F stored tank temperature.
Net Output is the space heating capacity based on normal piping and pickup
allowance of 15%.
Actual values may vary based on circulator flow rate, number of zones, water
and space heating demands. Numbers subject to change.
