The steamer is supplied with a 2 in tube connection at the bottom of the unit and a no-hub
connector, included (Figure 2-7).
•
When assembling the pipes and fittings of the drain outlet extension, apply a hardening type
pipe sealant to the threads, and thread them together FINGER TIGHT ONLY. DO NOT USE A
WRENCH.

Install Gas Supply Lines
a.
Gas Supply Requirements
1) Make sure the gas supply type matches the type of gas shown on the rating plate.
2)
Make sure that the gas supply pressure does not exceed 14” water column, and falls within
the acceptable gas pressure range shown below:
•
Natural gas pressure must be between 4½” – 14” water column.
•
Propane gas pressure must be between
11” – 14” water column.
b. Install Gas Supply lines
The installer/owner is responsible for furnishing and installing the gas supply lines, valves,
regulators, and accessories. When installing the gas supply lines and accessories, observe the
following:
1). The installation must conform with local codes, or in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1 (latest edition) or the Natural Gas Installation Code,
CAN/CGA-B149.1 or the Propane Installation Code, CAN/CGA-B149.2 as applicable.
2). THE GAS SUPPLY PRESSURE TO THE
STEAMER MUST NEVER EXCEED 14”
WATER COLUMN (½ psi). If the gas supply
pressure exceeds 14” water column; a
pressure regulator must be installed in the
gas supply plumbing to reduce the pressure
to the steamer.
3). Refer to Figure 2-8 for the recommended
layout of the gas supply lines. Refer to spec
sheet depending on which model you have,
Detail
A
for the location of the ¾ inch gas
inlet of the steamer.
4). Install a manual shut off valve between the
gas supply and the steamer. See Figure 2-8.
From now on this valve will be referred to as
the Main Manual gas valve.
5). It is recommended that a sediment trap (drip
leg) be installed in the gas supply line. See
Figure 2-8.
6). Use a pipe sealant compound, which is
resistant to LP gas.
