Utility Connections - Market Forge Industries ST-5G Installation Operation & Maintenance

GAS CONNECTION
1. The serial and rating plate on the unit indicates the
type of gas your unit is equipped to burn. DO NOT
CONNECT to any other gas types than the type spec-
ified.
2. A 3/4" NPT line is provided at rear for the connection.
Each compartment is equipped with an internal press
regulator which is set at 3.5" WC manifold pressure
for natural gas and 10" WC for propane gas. Use 1/8"
pipe tap n the burner manifold for checking pressure.
An adequate gas supply is imperative. Undersized or low
pressure lines will restrict the volume of gas required for
satisfactory performance. A stead supply of pressure, be-
tween 6" WC and 14" WC, for natural gas and between
11" WC and 14" WC for propane gas is recommended.
With all units operating simultaneously the manifold pres-
sure on all units should not show any appreciable drop.
Fluctuations of more that 25% on natural gas and 10% on
propane gas will create problems, affecting burner opera-
tion. Contact you local gas company for correct supply
line sizes.
Purge the supply line to clean out any dust, dirt or other
foreign matter before connecting the line to the unit. Use
pipe joint compound which is suitable for use with pro-
pane on all threaded connections. A manual gas shut-off
valve for each compartment is supplied with the unit.
Test pipe connections thoroughly for gas leaks.
All the connections must be checked for leaks, after the
unit has been put in operation. Use soapy water only for
testing on all gases. Never use an open flame to check
for gas leaks.
ELECTRICAL CONNECTION
WARNING
DO NOT CONNECT THE UNIT TO THE ELEC-
TRICAL SUPPLY UNIT AFTER GAS CONNEC-
TION HAS BEEN MADE.
120 VAC / 60 Hz / 1pH: Units with this rating are factory
supplied with a three-wire cord and three-prong plug
which fits any standard 120V, three-prong receptacle. A
separate 15 amp supply is needed for each unit.
PLUMBING CONNECTION
WARNING
PLUMBING CONNECTIONS MUST COMPLY WITH
APPLICABLE SANITARY, SAFETY AND PLUMBING
CODES.
Two water lines are provided, one for each compart-
ment. Connect water supply line to the 3/8" copper tube
in at the rear of the steamer. The 3/8" copper tube sup-
plies water to both the generator tank and condense live
steam enter the drain line.
DRAIN CONNECTION
The drain connection must be 1" IPS vertically down,
preferably with one elbow only, and maximum length of 6
feet, piped to an open air gap type drain.
CAUTION
PVC or CPVC are not acceptable materials for
drains.
In order to avoid any back pressure in the
steamer, DO NOT connect solidly to any drain
connection.
