1.5 GENERAL INFORMATION

FOR YOUR SATISFACTION, THIS FIREPLACE HAS BEEN TEST-FIRED TO ASSURE ITS OPERATION AND QUALITY! Maximum input is 26,000 BTU/hr for natural gas and propane. When the ﬁ replace is installed at

elevations above 4,500ft, and in the absence of speciﬁ c recommendations from the local authority having juris- diction, the certiﬁ ed high altitude input rating shall be reduced at the rate of 4% for each additional 1,000ft.

Maximum output for natural gas is 16,150 BTU/hr at an efﬁ ciency of 62%; and 16,150 BTU/hr for propane at an efﬁ ciency of 62%. Minimum inlet gas supply pressure is 4.5 inches water column for natural gas and 11 inches water column for propane. Maximum inlet gas pressure is 7 inches water column for natural gas and 13 inches water column for propane. Manifold pressure under ﬂ ow conditions is 3.5 inches water column for natural gas and 10 inches water column for propane.

This ﬁ replace is certiﬁ ed to be installed in an aftermarket permanently located, manufactured (mobile) home, where not prohibited by local codes.

No external electricity (110 volts or 24 volts) is required for the gas system operation.

This ﬁ replace is only for use with the type of gas indicated on the rating plate. This ﬁ replace is not con- vertible for use with other gases, unless a certiﬁ ed kit is used.

Expansion / contraction noises during heating up and cooling down cycles are normal and are to be expected. Change in ﬂ ame appearance from “HI” to “LO” is more evident in natural gas than in propane.

NOTE: The protective wrap on plated parts is best removed when the assembly is at room temperature but this can be improved if the assembly is warmed, using a hair dryer or similar heat source.

1.6 CARE OF GLASS

DO NOT CLEAN GLASS WHEN HOT! DO NOT USE ABRASIVE CLEANERS TO CLEAN GLASS.

2.0 VENTING

WARNING

Risk of fire, maintain specified air space clearances to vent pipe and appliance.

THIS FIREPLACE USES A 4" EXHAUST / 7" AIR INTAKE VENT PIPE SYSTEM.

Refer to the section applicable to your installation.

For safe and proper operation of the fireplace follow the venting instruction exactly. Deviation from the minimum vertical vent length can create difficulty in burner start-up and/or carboning. Under extreme vent configurations, allow several minutes (5-15) for the flame to stabilize after ignition. Vent lengths that pass through unheated spaces (attics, garages, crawl spaces) should be insulated with the insulation wrapped in a protective sleeve to minimize condensation. Provide a means for visually checking the vent connection to the fireplace after the fireplace is installed. Use a firestop, vent pipe shield or attic insulation shield when penetrating interior walls, floor or ceiling.

NOTE: If for any reason the vent air intake system is disassembled; reinstall per the instructions provided for the initial installation.

2.1 VENTING LENGTHS AND COMPONENTS

Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Metal-Fab venting components. Minimum and maximum vent lengths, for both horizontal and vertical installations, and air terminal locations for either system are set out in this manual and must be adhered to. For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the installation procedure provided with the venting components.

starter adaptor must be used with the following vent systems and may be purchased from the corresponding supplier:

Duravent W175-0053 Wolf Steel www.duravent.com

* For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the installation procedure found on the website for your venting supplier.

For vent systems that provide seals on the inner exhaust flue, only the outer air intake joints must be sealed using a red high temperature silicone (RTV). This same sealant may be used on both the inner exhaust and outer intake vent pipe joints of all other approved vent systems except for the exhaust vent pipe connection to the fireplace flue collar which must be sealed using the black high temperature sealant Mill Pac.

When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following termination kits: wall terminal kit GD222, GD222R, or 1/12 to 7/12 pitch roof terminal kit GD110, 8/12 to 12/12 roof terminal kit GD111, flat roof terminal kit GD112 or periscope kit GD201 (for wall penetration below grade). With flexible venting, in conjunction with the various terminations, use either the 5 foot vent kit GD220 or the 10 foot vent kit GD330.

For optimum flame appearance and fireplace performance, keep the vent length and number of elbows to a minimum. The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed and undamaged. Rigid and flexible venting systems must not be combined. Different venting manufacturer components must not be combined.

HORIZONTAL VENT RUN PLUS OFFSET IN FEET H

FIGURE 2.7c

The shaded area within the lines represents acceptable

values for H

and VT

For vent configurations requiring more than two 90° elbows the following formulas apply:

Formula 1: H Formula 2: HT + V

Example 2: V

= 2 FT

= 1 FT

= 1.5 FT

= V

= 6 FT

= 2 FT

= H

= .03 (four 90° elbows - 90°)

= .03 (360° - 90°) = 8.1 FT

= H

+ V

Formula 1: HT < 3V 3VT = 3 x 4.5 = 13.5 FT

< 3V

< 40 feet

+ V2 + V3 = 2 + 1 + 1.5 = 4.5 FT

+ H

= 6 + 2 = 8 FT

+ H

= 8 + 8.1 = 16.1 FT

= 16.1 + 4.5 = 20.6 FT

90°

FIGURE 2.7d

90°

16.1 < 13.5 Since this formula is not met, this vent configuration is unacceptable. Formula 2: HT < VT = 40 feet

20.6 < 40

Since only formula 2 is met, this vent configuration is unacceptable and a new fireplace location or vent configuration will need to be established to satisfy both formulas.
