NSTALLATION
To Install
1. Uncrate carefully. Report any hidden freight damage to the freight company immediately.
2. The pressure relief valve is located at the right rear of the unit. This area should be kept clear and should not be in an area
where operators will normally stand. The elbow on the relief valve should be turned toward the floor. A maximum 3 foot, 3/4"
diameter pipe may be used to extend to the floor, but must not be piped directly to a drain. It must vent to the atmosphere.
3. Set the unit in place. Be certain to maintain minimum clearances as stated above.
4. To level the unit use a spirit level in all directions on the top of the kettle (lid up). Adjust the bottom foot on each leg to
overcome an uneven floor.
5. Mark hole locations on floor through anchoring holes provided in flanged adjustable feet.
6. Remove appliance and drill holes in locations marked on floor and insert proper anchoring devices.
7. Set unit back in position and re-level left to right and front to back.
8. Bolt and anchor appliances securely to the floor.
9. Seal bolts and flanged feet with silastic or equivalent compound.
10. Appliance location must allow air supply to unit and obstruction free clearance for air opening into the combustion chamber.
11. Make service connections as indicated.
12. Check the pressure gauge on the front panel before operating. If the pressure gauge does not indicate green vacuum
zone (below 0 psi), see "Re-establishing Vacuum" section under SERVICE, after completing installation instructions.
GAS CONNECTION
The serial plate on the lower right side of the unit indicates the type of gas your unit is equipped to burn. Do NOT connect
to any other gas type.
A 3/4" NPT line is provided at the rear for the connection. Each unit is equipped with an internal pressure regulator
which is set for 4" W.C. manifold pressure for natural gas and 10" W.C. for propane gas. Use 1/8" pipe tap on 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 steady pressure, minimum 6" W.C. for natural gas and minimum 11" W.C. for propane gas, is
recommended. With all units operating simultaneously, the manifold pressure on all units should not show any appreciable
drop. Fluctuations of more than 25% on natural gas, and 10% on propane gas, will create pilot problems and affect burner
operating characteristics. Contact your 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. It is recommended that an individual manual shut
off valve be installed in the gas supply line to the unit. Use pipe joint compound which is suitable for use with LP gas on all
threaded connections. Test pipe connections thoroughly for gas leaks.
All connections must be checked for leaks, after the unit has been put in operation. Use soapy water only for
If applicable, the vent line from the gas appliance pressure regulator shall be installed to the outdoors in accordance
with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code CSA B149.1, as applicable.
If this equipment is being installed at over 2,000 feet altitude and was not so specified on order, contact service
department. Failure to install with proper orifice sizing may void the warranty.

testing on all gases. Never use an open flame to check for gas leaks.
