PLANNING YOUR INSTALLATION
QUESTIONS TO ASK THE LOCAL BUILDING OFFICIAL
Correct installation is critical and imperative for reducing fire hazards and perilous conditions that can arise when gas appliances function improperly. The appliance must be installed per manufacturers’ instructions.
Gas appliance equipment and installations must conform to appropriate local codes and applicable state and federal requirements. Familiarity with these requirements before installation is essential. Important considerations to discuss with local building officials include:
1.Applicable codes (i.e. Uniform Mechanical Code, State or Regional Gas Codes, National Fuel Gas Code)?
2.Local amendments?
3.Recognized testing lab: CSA / AGA.
4.Is a permit required - cost?
5.In some states or municipalities, a licensed gas fitter or plumber may be required to install this appliance. Check with your local building official for requirements in your area (i.e. Is a license required for installation of gas supply line)?
6.Maximum amount of gas pipe without a pressure test - type of test required?
7.Are below grade penetrations of the gas line allowed?
8.Is concealed gas piping allowed?
9.Specific requirements of concealed fittings?
10.Is rigid pipe to appliance required?
11.Allowed piping materials?
12.Shut-off valve required within 4 feet of the firebox?
13.May the shut-off valve be concealed?
14.Rooms where the installation is not allowed?
In the absence of local codes, installation should conform to the National Fuel Gas Code, also known at ANSI Z223.1- NFPA 54.

PLANNING YOUR INSTALLATION
MODELS L20 BF-2 AND L20 DVF-2 CLEARANCES TO COMBUSTIBLE MATERIALS
These appliances can be installed in most residential room configurations, parallel to a rear or adjacent wall, or in an alcove that allows for the minimum clearances to combustible surfaces. Your local building inspector should review your plans prior to installation.
When installing this appliance, provide adequate clearances around air openings and adequate clearances for purposes of servicing and proper operation.
As determined through the safety certification of this unit, a minimum clearance to combustible materials must be maintained around specific areas of the gas appliance.
(Refer to Figures 1 through 3)
The clearances listed here are minimum distances and only apply in the configuration shown. Do not use clearances from one installation configuration with clearances from another to obtain closer clearances.

MANUFACTURED (MOBILE) HOME REQUIREMENTS
Model L20 DVF-2 may be installed in an aftermarket permanently located, manufactured home, where not prohibited by local codes. When installed in Manufactured Housing the following supplemental requirements must be met:
The appliance must be secured to the floor. Use the (3) ¼”-20x2 ¾” bolts (which secured appliance pedestal base to the wooden pallet) for securing appliance to the manufactured home floor.
The appliance must be grounded to the chassis of the manufactured home. Use a No. 8 or heavier copper wire at least 18" in length.
Model L20 BF-2 is NOT approved for Manufactured Home installations.
IMPORTANT NOTES:
The structural integrity of the manufactured home floor, walls, ceiling and roof must be maintained.
A manufactured (mobile) home installation must conform with the Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280, or, when such a standard is not applicable, the Standard for Manufactured Home Installations, ANSI / NCSBCS A225.1, or standard for Gas equipped Recreational Vehicles and Mobile Housing, CSA Z240.4.

Detail
Maximum total offsets allowed: Not to exceed 180 degrees. Maximum allowable horizontal pipe run is 12 feet.
With 2 feet of vertical pipe installed from the appliance (* see note), a 2 foot maximum horizontal run allowed. For installations with more than 2 feet of vertical pipe, calculate allowable horizontal run as indicated in applicable illustration above.
See page 10 for Vent Termination Requirements.
Also see pipe manufacturers instructions for additional vent installation requirements. Horizontal vent clearances: 3“ minimum top 1“ minimum on bottom and sidewalls. Vertical vent clearances: 1” minimum.
Install vent support brackets every 4 feet of vertical pipe unless otherwise specified by vent manufacturer.
* Note: If using Propane Gas (LP), it may be necessary to install (as a minimum) 3 feet of vertical pipe from the appliance prior to an offset to ensure optimum product performance. This may be necessary due to variations in vent configuration and other numerous factors which affect exhaust flow and air delivery such as BTU value, ambient temperature, wind conditions, altitude, etc.

Snorkel Caps: These are elongate vent termination caps, which incorporate the principles of natural draft into a horizontal installation. Two styles are common, 14” and 36” (Cap height). They enhance draft and relieve backpressure by creating natural draft in the snorkel.
Horizontal Caps: This 13 ½” square horizontal cap is placed on the outer wall of the dwelling. Not to be within 9” of an air inlet or within 12” of the ground. It requires a minimum 2’ rise on the interior pipe.
•Vertical Termination Cap: Low profile and high wind caps can only be used on vertical pipe installations.

INSTALLATION - MODEL L20 DVF-2 ONLY
Direct Vent Retrofit Of Existing Chimney System - An existing Class-A (wood-burning) Metal Chimney or Masonry Chimney can be converted to a direct vent system. Use one of the following chimney conversion kits listed below. Have the existing chimney system inspected by a professional prior to the conversion. If using Simpson Dura-Vent brand liner kit, see “IMPORTANT” note at the top of page 8. The chimney conversion should not be applied to the portion of the vent system that is in the room of the appliance. Use only Co-Axial direct vent pipe (4” inner pipe, 6 5/8” outer pipe as listed on page 8) from the appliance to the retro-connector into converted flue system. Adhere to all specifications shown on pages 6 and 7 regarding clearances to combustibles, vertical and horizontal vent length minimums and maximums, etc. Read all instructions in this manual and provided by vent manufacturer with kit carefully before starting the installation. Failure to follow the instructions may create a fire or other safety hazard, and will void the warranty.
