G. FREEZE PROTECTION FLUIDS
NEVER
use automotive or standard glycol antifreeze, or ethylene glycol made for hydronic systems, with this boiler. Use only inhibited
propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is toxic and can attack gaskets and
seals used in hydronic systems.
Consider boiler piping and installation when determining boiler location.
NOTE:
Damages resulting from incorrect installation or from use of products not approved by HTP, Inc. ARE NOT covered by warranty.
H. HIGH ELEVATION INSTALLATIONS
Natural gas at high elevation might contain less heating value than typical 1,000 BTU/cu ft and therefore can cause improper air / gas
mix leading to improper combustion. For natural gas installations above 3,000 ft, call your gas provider to determine the heating value
of the supplied natural gas.
