INTRODUCTION

Model VGL450 series is a radiant heat decorative gas appliance that uses a millivolt gas control valve and a pilot ignition system.

This appliance requires a 4" B-1 type venting system.

4" B-1 type vent NOT supplied by DESA. Check with your "B" vent instructions for installation guidelines.

WARNING: This gas appliance must not be connected to a chimney flue servicing a solid fuel burning appliance.

• Model VGL450N uses N ATURAL GAS ONL Y.

• Model VGL450P uses PROPANE GAS ONLY.

If you have any doubts as to which gas your particular unit is approved and tested for, please check the AGA/CGA rating plate located behind the access panel (Figure 1, page 2).

BEFORE YOU BEGIN

Before beginning the installation of your appliance, read these instructions through completely.

This DESA appliance and its approved components are safe when installed according to this installation manual and are operated as recommended by DESA. Unless you use DESA approved components tested for this appliance, YOU MAY CAUSE A FIRE

HAZARD!

The DESA warranty will be voided by, and DESA disclaims any responsibility for the following actions :

A) Modification of the appliance or any of

the components manufactured by DESA unless otherwise permitted in writing by DESA.

B) Use of any component part not ap-

proved by DESA in combination with this DESA appliance.

C) Installation and/or operation in a man-

ner other than instructed in this manual.

D) The burning of an ything other than the

type of gas approved for use in this gas appliance.

This appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/

NFPA 70 or the CSA C22.1 CANADIAN ELECTRICAL CODE for Canada.

The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code ANSI Z223.1 or with the current CAN/CGA-B149[.1 OR .2] Installation Codes for Canada.

This appliance complies with ANS Z21.50-

1998 and CAN/CGA 2.22-M98 Standard as a VENTED DECORATIVE GAS APPLIANCE and is tested and listed by the Ameri- can Gas Association and Canadian Gas Association.

CAUTION: Installation and repair should be done by a qualified service person. The appliance should be inspected before use, and at least annually by a qualified service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding material, pet hair, etc. It is imperative that the control compartments, burners and circulating air passageways of the appliance be kept clean.

NOTICE: This appliance is not intended to be used as a primary source of heat.

SELECTING LOCATION

To determine the safest and most efficient location for your appliance, you must take into consideration the following guidelines:

1. The location must allow for proper clearances (see Clearances, page 4 ).

2. Consider a location where heat output would not be affected by drafts, air conditioning ducts, windows or doors.

3. A location that avoids the cutting of joists or roof rafters will make installation easier. Figure 3 sho ws a plan view of a few common locations.

Flush installations are recommended where living space is limited or at a premium, and since the space required to enclose the appliance would be located beyond an outside wall, this would also reduce the cutting of joists, roof rafters and such. Check local codes for any restrictions.

Projected installations can extend any distance into the room. A projection may be ideal for a new addition on an existing, finished wall.

Corner installations make use of space that may not normally be used and provides a wider and more efficient range for radiant heat transference.

Internal wall installations provide a discreet option for room separation and can also be ideal as an addition to an existing wall.

Also, in selecting a location, the following precautions must be observed:

1. Do not connect this appliance to a chimney system used for a solid fuel burning fireplace.

2. Install in an area providing ventilation and adequate combustion air.

3. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.

4. NEVER obstruct the front opening of the appliance or the flow of combustion and ventilation air. Keep control compartments accessible.

5. Do not locate in the vicinity where gasoline or other flammable liquids may be stored. The appliance area must be kept clear and free from these combustible materials.

VENTING INSTALLATION

A 4" B-1 Type Gas Vent Pipe is a double wall, unitized venting system (not supplied) which must be installed during the rough framing of the appliance. Any B-1 Type gas vent system may be used for proper venting as long as it is installed per the manufacturer's recommendations.

This appliance has been supplied with a 4" dia. starting collar for a snug fit. Slide B-1 vent pipe over starter pipe until fully seated.

Fasten this first section of "B" vent pipe by running a 3/4" long sheet metal screw through outer wall of pipe until secure. (see Figure 12).

The B-1 vent pipe must be properly terminated per manufacturer's instructions.

Check with your B-1 Vent installation instructions regarding multiple venting into a common flue.

IMPORTANT:

minate in an attic space. Minimum height for complete system (vent

termination and appliance) is 12 feet. Maximum horizontal run of B-1 type vent

pipe can be no greater than 75% of total vertical height of the vent.
