1.5 Locating the Appliance
The appliance should be located to provide
clearances on all sides for maintenance and inspection.
It should not be located in an area where leakage of
any connections will result in damage to the area
adjacent to the appliance or to lower floors of the
structure.
When such a location is not available, it is
recommended that a suitable drain pan, adequately
drained, be installed under the appliance.
The appliance is design certified by CSA-
International for installation on combustible flooring;
in basements; in closets, utility rooms or alcoves.
Mighty Therm2 Boilers or Water Heaters must
never be installed on carpeting. The location for the
appliance should be chosen with regard to the vent
pipe lengths and external plumbing. The unit shall be
installed such that the gas ignition system components
are protected from water (dripping, spraying, rain, etc.)
