Residential Gas Water Heaters
DIRECT VENT
Features
DIRECT VENT DESIGN
One-pipe, dual-channel closed system draws all make-up air from outside
the home, eliminating problems caused by insufficient indoor
ventilation and is FVIR compliant.
Horizontal air intake and venting on all models up to 80 inches from
outside wall with no electrical power needed.
INTELLIGENT CONTROL LOGIC
The internal microprocessor provides enhanced operating parameters and
tighter differentials for precise sensing and faster heating response to optimize
performance
DYNACLEAN™ DIFFUSER DIP TUBE
Helps reduce lime and sediment buildup, maximizes hot water output.
Made from long-lasting PEX cross-linked polymer.
SELF-POWERED ELECTRONIC GAS VALVE
Uses a thermopile to generate the power needed to operate the electronic
gas control without requiring an external power source.
®
DIAGNOSTICS
The electonic gas control incorporates and LED status indicator that monitors
system operation and service diagnostics.
PUSH BUTTON PIEZO IGNITOR
Makes lighting pilot fast and easy with one hand push button spark
ignition.
HEAT TRAP NIPPLES
Factory-installed.
DURABLE TAMPER-RESISTANT BRASS DRAIN VALVE
PERMAGLAS
Provides corrosion resistance.

Important! Vent Installation and Termination Requirements
Maximum horizontal vent distance is 80” to outside of exterior wall.
Minimum horizontal vent distance is 17” to outside of exterior wall.
Vent pipes may be trimmed (cut) for short vent installations.
For vent installation less than 30” the vent restrictor is required.
Place restrictor over the flue outlet on heater before installing the outlet
vent pipe to the heater.
Recommended installation height for the heater vent pipe should be
68” for 40 gallon models and 76” for the 50-gallon and 75-gallon
models (vent height).
Offset Vent Arrangement
1. When replacing an existing direct vent model,
the new vent pipe may drop from the minimum
vent height as much as 7 1/4” to exit through the
existing vent opening in the exterior wall.
2. Vent may have one horizontal 90 degree turn before
exiting through exterior wall (Do not combine both
offset vent arrangements in one installation) (See
examples in the installation manual)
High Rise Vent Arrangement
3. When vent termination is more than 80” above the
base of the heater. The horizontal vent run must be
a minimum of 22” from the center of the heater to
the outside exterior wall surface. (See example in the
installation manual)
Vent termination clearance hole through the exterior
wall should be approximately 7” diameter.
Snow accumulation and drifting should be considered
when locating the termination.
An optional wire grill vent cap protector is available
through the parts department. Part number 9006627005.
See the installation manual for complete installation
and venting requirements.
