This boiler series is classified as a Category 1 and the
3.
vent installation shall be in accordance with Part 7 of the
National Fuel Gas Code noted above when installed in
the United States. In Canada refer to the CAN1-B149.1
and or B149.2 Installation Codes for Gas-Burning Equip-

This boiler has met safe lighting and other performance
4.
criteria with the gas manifold and control assembly on the
boiler per the latest revision of ANSI Z21.13/CGA 4.9.
The boiler shall be installed such that the gas ignition
5.
system components are protected from water (drip-

Locate boiler on level, solid base as near the chimney
6.
as possible and centrally located with respect to the heat
distribution system as practical.
Allow 24 inches at the front and right side for servicing

and cleaning.
When installed in a utility room, the door should be wide
8.
enough to allow the largest boiler part to enter, or to

mum clearances to combustible construction are:
TOP ........................................................... 18 IN.
FRONT ...............................................ALCOVE *
FLUE CONNECTOR ................................... 6 IN.
REAR ........................................................... 8 IN.
CONTROL SIDE .......................................... 9 IN.
