Installation Guidelines
Location
The location of the heater must be large enough to provide safety clearances. Objects and
materials closer to the heater than 6” must be lined with high density, heat retardant
insulation and covered with metal (stainless steel, aluminum, etc.). Another alternative is
using ceramic tiles. Particular care must be taken to protect the surfaces close to the first
section of flue pipe.
The install location should also take into account the length and configuration of the flue
stack. It is generally preferable that the flue stack be a long straight run. If you have the
option, avoid having to use elbows.
