exceeds 12.0 inches of water column pressure.
IMPORTANT: A water column pressure of 3.5
to 4.0 inches for natural gas and 11.0 inches for
L.P. dryers is required at the gas valve pressure
tap of each dryer for proper and safe operation.
A Vs inch N.P.T. plugged tap, accessible for a
test gauge connection,
must be installed in the
main gas supply line immediately upstream of
each dryer.
IMPORTANT: Pipe joint compounds that resist
the action of natural and LR gases must be
used.
IMPORTANT: Test ALL connections for leaks by
brushing on a soapy water solution (liquid
detergent works well).
WARNING: NEVER TEST FOR GAS LEAKS
WITH A FLAME!!!
ALL components/materials must conform to
National Fuel Gas Code Specifications ANSI
Z223.1-LATEST EDITION, or in CANADA, the
Canadian Installation Codes CAN/CGA-
B149.1-M91 (Natural Gas) or CAN/CGA-
B149.2-M91 (LR Gas) or LATEST EDITION.
It is important that gas pressure regulators
meet applicable pressure requirements, and
that gas meters be rated for the total amount of
appliance Btu’s being supplied.
IMPORTANT: The dryer and its individual shut­
off valve must be disconnected from the gas
supply piping system during any pressure
testing of that system at test pressures in
excess of 1/2 psig (3.5kPa).
NOTE: The dryer must be isolated from the
gas supply piping system by closing its indi­
vidual manual shut off valve during any pres­
sure testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig
(3.5 kPa).
