(ULC-S636 pipe must be used for Canada.)
* Based on simultaneous showers using 2.5 GPM flow rate
pre-mixed with cold water line. Flow rates vary depending
on temperature of incoming cold water and water heater set
temperature. Refer to flow rate curves for accurate sizing.
Uniform Energy Factor based on Department of Energy (D.O.E.)
requirements.
All models are available in Natural Gas and Propane (LP). For
Propane replace the N with P when ordering.
SCAQMD 1146.2 compliant.

Proper gas pressure must be ensured to supply tankless gas
water heaters – up to 199,900 BTU/h for ESGH-95 models,
up to 157,000 BTU/h for ESGH-84 models. (Consult your gas
supplier)
