Gas Hose - L.B. White Bloom 400 Owner's Manual And Instructions

Regulator and Gas Hose
Regulator Requirements
The low pressure regulator supplied at the heater's gas
inlet regulates a gas supply inlet pressure of 13.5 inches
W.C. (3.36 kPa) maximum down to a minimum gas sup-
ply pressure of 7.0 inches W.C. (1.74 kPa).
With pressures between the maximum and minimum, the
regulator reduces the pressure down to the proper burner
manifold pressure for either LP or natural gas.
Pressure higher than the maximum inlet pressure
requires a regulator of proper capacity and pressure set-
ting supplied by the installer to ensure proper operation
of the heater.
Regulators are available as an accessory for either LP or
natural gas applications.
LP Gas: part number 500-132229
Natural Gas: part number 500-132228
These are to be used as seconds stage regulators, and
shall be installed so the regulator's vent is directed down.
For LP Gas:
-- If the gas installation will be plumbed using 5 -10 PSIG/
34.5 -68.9 kPa, install the regulator on the gas line to
reduce high pressure to low pressure required at the
heater's gas inlet.
For Natural Gas:
-- Use the regulator ONLY if the supply pressure is 2
PSIG/13.8 kPa or greater.
The regulator shall be connected to the gas supply using
the proper plumbing devices.
Gas Hose Requirements
This heater requires a gas hose of 3/4 in. (1.9 cm)
minimum diameter for lengths up to 15 ft. (4.6 m). Longer
hoses will potentially require larger diameters.
The 15 ft. (4.6 m) hose is available from L.B. White as
part number 500-25965, and is ordered as an accessory
(not included with the heater).
Connect the gas hose to the low pressure regulator
at the heater's gas inlet, using pipe thread compound
that is resistant to LP and natural gas on the threaded
connections.
Connect its opposite end to the gas supply with appropri-
ate fittings.
