VENTING INSTALLATION INFORMATION SS38 Direct Vent Gas Stove

WARNING

Read all instructions completely and thoroughly before attempting installation. Failure to do so could result in serious injury, property damage or loss of life. Operation of improperly installed and maintained venting system could result in serious injury, property damage or loss of life.

INSTALLATION PRECAUTIONS

Consult local building codes before beginning the installation. The installer must make sure to select the proper vent system for installation. Before installing vent kit, the installer must read this stove manual and vent kit instructions.

Only a qualified installer/service person should install vent- ing system. The installer must follow these safety rules:

•Wear gloves and safety glasses for protection.

•Use extreme caution when using ladders or when on rooftops.

•Be aware of electrical wiring locations in walls and ceilings.

The following actions will void the warranty on your vent- ing system:

•Installation of any damaged venting component.

•Unauthorized modification of the venting system.

•Installation of any component part not manufactured or approved by MHSC.

•Installation other than permitted by these instruc- tions.

NOTICE	Failure to follow these instructions will
	void the warranty.
WARNING	This stove must be vented to the outside.
	The venting system must NEVER be
	attached to a chimney serving a separate
	solid fuel burning appliance. Each gas
	appliance must use a separate vent system.
	Do not use common vent systems.
	Horizontal sections of this vent system
	require a minimum clearance of 2" from
WARNING	the top of the pipe and 1" minimum to the
	sides and bottom. Vertical sections of this
	system require a minimum of 1" clearance
	to combustible materials on all sides of the
	pipe. Only a 1" clearance is required where
	the vent passes through the nearest vertical
	wall.

INSTALLATION PLANNING

There are two basic types of direct-vent installation:

•Horizontal Termination

•Vertical Termination

It is important to select the proper length of vent pipe for the type of termination you choose. It is also important to note the wall thickness.

FOR HORIZONTAL TERMINATION

Select the amount of vertical rise desired. The horizontal run of venting must have 1/4" rise for every 12" of run towards the termination.

You may use up to three 90° elbows in this vent configu- ration. Refer to Horizontal Termination Configurations on Page 13.

WARNING	Never run the vent pipe level or downward.
	This may cause excessive temperatures
	which could cause a fire.

For vertical termination

Measure the distance from the stove flue outlet to the ceil- ing. Add the ceiling thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the roof line. You may use one or two 90° elbows in this vent configuration. Refer to Vertical Termination Configurations on Page 16.

NOTE: You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when using 45° elbows. The appliance is approved for use with three 90° elbows maximum or a combination of 90° and 45° elbows up to a maximum of 270°.

For two-story applications, firestops are required at each floor level. If an offset is needed in the attic, additional pipe and elbows will be required.

You may use a chase with a vent termination with exposed pipe on the exterior of the house. Refer to Installing Vent System in a Chase.

It is very important that the venting system maintain its bal- ance between the combustion air intake and the flue gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.
