NOTE: Use only MetalBest Chimney System Listed components

and accessories. Do not use pipe by itself or attempt to fabricate

your own support or accessories.

CAUTION: IF YOU ARE BURNING COAL

Some types of coal in certain designs of stoves may, in rare instances,

cause corrosion of the inner parts of the MetalBest Chimney System.

Inspect and clean your chimney frequently to keep it free of coal, ash and

soot deposits. Also see “Sizes and Applications” section. If damage to the

flue is observed, contact your Selkirk MetalBest dealer or Selkirk

MetalBest Customer Service (1-800-992-VENT) with a description of

your chimney problem.

The MetalBest Chimney System is not recommended if you are burning

ocean driftwood. The salt in this wood may cause product failure.

*If you are installing any of these parts in packages marked*, you should

receive the proper instructions in the package. You may also request a

complete set of instructions from your dealer. This sheet of general instruc-

tions is furnished with all UL listed chimney supports. It covers important

safety precautions in the installation, operation and maintenance of your

appliance and chimney. Anyone installing a chimney should review this

sheet as well as those furnished with the other parts of the chimney

system. Selkirk MetalBest chimney parts LISTED and produced under the

Factory Inspection and Follow-Up program of Underwriters' Laboratories,

Inc. carry the LISTING MARK illustrated here.

SPECIAL WARNING ON CELLULOSE INSULATION

Cellulose insulation in direct contact with a hot chimney can ignite and smolder, and can set fire to ordinary wood framing materials. The AIR SPACE ONLY

precaution applies to all blown-in or loose fill insulations, but is especially applicable to cellulose insulation, which may be made from old newspapers or

other cellulose materials. The Attic Insulation Shield or a suitable enclosure with appropriate fire stops must be used to keep all insulation the proper distance

away from the chimney.

fully enclosed at 2 inches minimum AIR SPACE clearance to combustibles,

including framing lumber, drywall, plaster, plywood and other building mate-

rials classed as combustible. For support framing, see table on back page.

AIR SPACE ONLY

The minimum clearance to MetalBest Chimney System pipe means AIR

SPACE ONLY. The 2 inch clearance to pipe, and the spaces around sup-

ports must not be filled with any type of insulation. In attics with blown-in or

batt insulation, the chimney must either be fully enclosed or an Attic Insula-

tion Shield must be used to create and maintain the proper minimum air-

space.

SIZES AND APPLICATIONS

The MetalBest Chimney System is made in 5”, 6", 7", 8", 10", 12", and 14"

sizes. The four smaller sizes conform to the current edition of UL-103

Standard Type HT requirements. All seven sizes comply fully with the

requirements of the 9th Edition of UL Standard 103. Chimneys installed in

accordance with these instructions will comply with national safety stan-

dards such as NFPA 31, 54 and 211. The MetalBest Chimney System may

be used for gas, wood and liquid fuel fired stoves, fireplace stoves, central

furnaces, floor furnaces, steam and hot water boilers, unit heaters and

water heaters. It may also be used for masonry fireplaces.

These MetalBest Chimney Systems are designed for gravity venting

only. They are usable on any appliance having a power burner (such as oil

furnace) if that appliance operates with neutral or negative draft at its

outlet.

Non-residential appliances which may cause positive pressure in the chim-

ney should use a Selkirk Model PS or IPS system.

The MetalBest Chimney Systems, sizes 10", 12", 14", are ideal for vent-

ing gas (natural and LP), #2 oil, and open front wood burning appliances.

MetalBest Chimney Systems (MCS) consist of the following Models - UT

(Ultra Temp), ST (Sure Temp), GT (Galva Temp), SG Plus and SSII.

The complete part number is prefixed with the ID size, in inches, followed

by one or two letters identifying the system to which it belongs, followed

by the actual part identifier.

All accessory parts for the MetalBest Chimney System (all models) in-

clude a letter “T” in the prefix and may be used with all Models unless

otherwise indicated.

All Model SSII chimney sections (straight lengths, tees, elbows) also con-

tain the letter “T” in the prefix.

All Model UT, ST and GT chimney sections (straight lengths, tees, elbows)

contain the letters “UT”, “ST”, and “GT”, respectively in the prefix.

All Model SG Plus chimney sections (straight lengths, tees, elbows) con-

tain the letters “GP” in the prefix.

Fig. 1, 2, and 3 show the names and locations of commonly used chimney

parts. These figures use only the last portion of the part number. The

complete part number is prefixed with I.D. size, followed by chimney model

and part number.

FIRST Look for a label or nameplate attached to the appliance which bears the mark or name of a well-known safety testing organization* or laboratory. SECOND Don't buy an appliance which is bigger than necessary. THIRD Look or ask for complete installation, operating and maintenance instructions for the appliance.

because the galvanized zinc coating is ineffective once it has been overheated. 11. Operating the stove, heater or fireplace when the connector is red hot is very dangerous. This indicates overfiring or a chimney fire. Stop firing, close the dampers, let things cool off, and keep watching for problems on nearby walls and furnishings. 12. The slope of the horizontal portion of a connector of 1/4 inch per foot is sometimes a building code requirement.

2” Back-Up Enclosure * Strip Minimum Clearance Chimney Pipe which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire. With coal which can burn with a smoky fire, this smoke also condenses in the chimney to form soot.
