are available from CSA Information Services, 1-800-463-6727. Local authorities
having jurisdiction should be consulted before installation is made to verify local
codes and installation procedure requirements.
Installations in aircraft hangars should be in accordance with ANSI/NFPA No. 409
(latest edition), Standard for Aircraft Hangars; in public garages in accordance
with ANSI/NFPA No. 88A (latest edition), Standard for Parking Structures; and for
repair garages in accordance with ANSI/NFPA No. 88B (latest edition), Standard
for Repair Garages. In Canada, installations in aircraft hangars should be in accor-
dance with the requirements of the enforcing authorities, and in public garages in
accordance with CSA B149 codes.
If the heater is being installed in the state of California, the installer MUST attach a
warning label on the outside of the access door. Find the California Warning label,
P/N 196977, in the plastic bag with this installation manual. Select a location on the
heater access panel. Be sure the surface is clean and dry and adhere the label.
If the heater is being installed in the Commonwealth of Massachusetts, this unit
must be installed by a licensed plumber or licensed gas tter.
Use the throw data and location information in this section; clearances and dimen-
sions in Paragraph 4; weights and hanging instructions in Paragraph 6; and piping,
venting, and condensate drain requirements in Paragraph 7, to determine where
to suspend the heater. Due to possible condensate freezing in the secondary heat
exchanger and/or condensate drain, this heater should not be used in an applica-
tion where the space temperature of the location is below 50°F.
