Before Set-up
Do not use fan blower termination or
boiler enclosure paneling to lift/move
boiler into its installation location.
The boiler is shipped on a wooden pallet
in a cardboard crate. Crate and wooden
pallet must be removed.
Before placing boiler in its installation
location, ensure all necessary
accessories are installed.
Installation on Combustible Floor
1. Verify that base size and material are
in conformity with local codes.
2. Locate t he base so that the minimum
clearances of boiler to combustible
materials are maintained.
3. Base must be constructed of hollow
concrete blocks, minimum height
4”/100 mm, and covered with sheet
metal at least 24 ga. thick.
4. The base must extend beyond the
boiler enclosure by at least
6”/150 mm on all sides.
5. The blocks must be placed so as to
provide an unbroken concrete surface
under the boiler, with the hollows
running continuously and horizontally
to allow air circulation.
IMPORTANT
The boiler must be installed in such a
way that gas ignition system
components are protected from water
(spraying, splashing, etc.) during
boiler system operation and service.
