C. CLEARANCES FOR SERVICE ACCESS
1. If you do not provide minimum clearances, it
might not be possible to service the water heater
without removing it from the space. (See Fig. 3-
1 at right)
D. RESIDENTIAL GARAGE INSTALLATION
Precautions
Take the following special precautions when installing the water heater in a residential garage. If the
heater is located in a residential garage, per ANSI Z223.1, paragraph 5.1.9:
•
Place the Phoenix with a minimum of 18 inches above the floor of the garage to the bottom of the
heater to ensure the burner and ignition devices will be no less than 18 inches above the floor.
•
Locate or protect the water heater so it cannot be damaged by a moving vehicle.
E. EXHAUST VENT AND INTAKE AIR VENT
The Phoenix requires a special vent system, designed for pressurized venting. Phoenix Water
Heaters are rated ANSI Z21.10.3 Category IV (pressurized vent, likely to condense in the vent).
You must also install air intake piping from outside to the water heater flue adaptor. The resultant
installation is categorized as direct vent (sealed combustion).
Note: To prevent combustion air
contamination see Table 3-2 in this section for examples of areas to avoid when con-
sidering exhaust vent and intake air vent termination.
