Installation Instructions

B. Teflon tape acts as a lubricant and greatly

reduces the pipe wrench turning force re-

quired to seal the threads.

Take care not to overtighten threads as

this can damage the valve.

C. Good piping practice dictates that piping be

independently supported, so that valve bodies

are not placed in a bind. In addition, large

valves may require support.

D. Clean pipe lines of foreign materials before

installing valve into line.

For new installations, a gas filter or strainer shall be

installed in the fuel gas piping to protect the

downstream safety shut-off valves.

NFPA 86C-4-2.4.3 (1999)

NFPA 86D-4-2.4-3 (1999)

If normal inlet pressure to the fuel pressure regula-

tor immediately upstream from the valve exceeds

the valve’s pressure rating, a relief valve shall be

provided and it shall be vented to a safe location.

E. Mount valve so that open/shut window

indicator [1] will be visible to your operating

personnel. The open/shut window indicator

should never face downward. With Maxon

electro-mechanical top assemblies, the motor

access side plate [2] should always be

vertical to the ground. Valves are usually

installed in horizontal piping; however, other

1. Read complete instructions before proceeding

and do not discard packing materials until any/all

loose items are located. Also, make sure that the

installation of the Maxon valves will be in compli-

ance with all applicable governmental, insurance

and/or agency requirements or codes, such as

NFPA-70, National Electric Code, CSA C22.1,

Canadian Electric Code, etc.

2. General considerations:

A. Prior to shipment, each valve is operated

electrically and cycled at rated and 1-1/2

rated pressure while being leak tested. Every

Maxon valve is operationally tested and

meets the requirements of ANSI B16.104

Class VI Seat Leakage when it leaves our

plant.

B. Inspect your valve for any shipping damage.

Contact Maxon Corporation with the valve’s

serial number (printed on the valve's name-

plate) for replacement and/or repair parts.

C. Read the nameplate on your valve. This

gives the maximum pressure, temperature

limitation, voltage requirements and service

conditions of your specific valve. DO NOT

exceed nameplate ratings.

D. Select mounting location carefully. Your

Maxon valve is designed to operate for many

years if installed in a location that is cool,

clean and dry.

3. Pipe the valve in the direction of the flow arrow

[3] on the valve body. The Maxon valve body can

shut off flow in one direction only.

A. Remove all thread and flange protectors

before installing valve in your service line.

Also, make sure that the installation of the Maxon valves will be in compliance with all applicable governmental, insurance and/or agency requirements or codes, such as NFPA-70, National Electric Code, CSA C22.1, Canadian Electric Code, etc. 2.

The top assemblies of all Maxon valves are field rotatable to allow installations involving conflicts with these mounting restrictions. F. Main system shut-off should always use a manual leak-tight upstream fuel cock. G. Time lag between valve action and fluid flow (or flame response) is reduced if valve is located near the burner (or outlet). 4.

Remove the two body bolts [4] screwed up from the bottom (were partially unscrewed in step 5). 8. Carefully rotate top assembly to the desired position in a plane parallel to the top of the valve body casting. Rotate the top housing about 30° beyond this position, and then rotate it back. Reposition the top housing back down onto the valve body casting.

Electro-Mechanical Valves Page 6100-S-5 Operating Instructions Refer to appropriate catalog bulletin and specification page for operating sequence applying to your specific valve. Never operate valve until all essential allied equipment is operative and any necessary purges completed. Failure of electro-mechanically operated valve to operate normally indicates that it is not powered. Check this first! Then check internal holding solenoid and/or motor operator.

Page 6100-S-6 Electro-Mechanical Valves Maintenance Instructions Maxon valves are endurance tested far in excess of the most stringent requirements of the various approval agencies. They are designed for long life even if frequently cycled, and to be as maintenance-free and trouble-free as possible. Every Maxon valve is operationally tested and meets the requirements of ANSI B16.104 Class VI Seat Leakage when it leaves our plant.

For normally open versions (STOM, STO-A, Fig. 1 & 2), reverse switch nomenclature. (VOS becomes VCS and vice versa.) General: Shut off fuel supply upstream of valve, then de-energize valve electrically. – Remove top or side cover to provide access, being careful not to damage gasket.

(See sketch below.) 1. Mount both valves in fuel line with center to center spacing as originally specified, and blocking valve (without handle) downstream of main valve (with handle). 2. Check valve alignment to be certain that operating wheels lie in the same plane. 3.

A wheel is mounted onto the handle of the valve. The attached chain is weighted on one end and has a paddle handgrip on the other. Once the valve is electrically energized, pulling down on the paddle will open normally closed versions or close normally open versions.

Instructions provided by the company and/or individuals responsible for the manufacture and/or overall installation of complete system incorporating Maxon valves take precedence over these provided by Maxon. If Maxon instructions conflict with any codes or regulations, contact Maxon Corporation before attempting this procedure.
