Outdoor Conversion Manual 5
When selecting an installation location, you must ensure that all water heater guidelines and
clearances will be met. Consider the installation environment, water quality, and the need for freeze
protection. Refer to the installation sections in the “Tankless Water Heater Installation and Operation
Manual” for gas line, water lines, electrical and condensate disposal requirements.

IMPORTANT
When an exhaust outlet is blocked by snow or other objects, the water heater may run at a limited
capacity, or can be shut down with an error code. Remove snow or other objects around the
exhaust outlet. External hot and cold water pipes and valves should be insulated to prevent freezing.
To protect pipes and valves from severe cold conditions, additional protection should be used.
Use the following guidelines to ensure you have selected the correct location for the water heater:
• The water heater is not exposed to ambient temperatures lower than -4°F (-20°C) with direct wind
exposure.
• The water heater is not exposed to corrosive compounds in the air.
• The water heater location complies with the required clearances.
• The planned combustion air intake and exhaust outlet locations meet the required clearances.
• The water supply does not contain chemicals or exceed total hardness that will damage the heat
exchanger.
• A standard 3-prong 120 VAC, 60 Hz properly grounded and weather-resistant power outlet is
available.
• The installation must conform with local codes or, in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, and/or CSA B149.1, Natural Gas and Propane
Installation Code.
