COMBUSTION AIR SUPPLY
Installation of this water heater requires that provisions be made to supply
adequate air for combustion and ventilation. If the building is unusually tight or if
this water heater is installed in a small room, provisions for additional makeup air
must be provided. This air must be supplied through two permanent openings
located so that the lower edge of the lower opening is 6 inches below the top of
the enclosure.
The minimum free air area for such openings shall not be less than one square
inch per 1000 BTU/HR of the total input rating of all appliances in that enclosure of
100 square inches, whichever is greater. For outside air, in the absence of local
codes, refer to the National Fire Protection Standard for Oil Burning Equipment
NFPA No. 31 (latest edition), or CSA B139 (latest edition).
ELECTRICAL CONNECTIONS
This water heater is normally wired for 120Volts / 15amp / 60Hz and shall be
electrically grounded in accordance with local codes, or in the absence of local
codes, with the National Electrical Code, ANSI/NFPA No. 70 (latest edition), or
Canadian Electrical Code, Part 1 (latest edition).
If any of the original wiring must be replaced, replacement shall be with 105°C
(221°F) wire or equivalent.
