mantel starng at 44” (1118mm) above the oor.

• As referenced in FIGURE 3.5, clearances to combusbles sided in the front (such as a mantel leg or a sidewall) is 3” (76mm)

from the masonry replace opening with an unlimited projecon.

• The mantel project shown is the minimum mantel allowed. You are able to increase the mantel projecon by 1” (25mm) out

by going 1” (25mm) up. An example of this would be if you wanted a 9” (229mm) mantel you would need to go another

3” (76mm) higher than the minimum height shown. The 9” (229mm) mantel would be 43-1/2” (1105mm) o the oor.

3.6 Outdoor Covered Gas Stove Installaon

An outdoor covered gas stove installaon allows a gas stove to be installed in an outdoor covered area, where the appliance is

protected from direct precipitaon.

Follow the instrucons and illustraons in this secon for installaon procedures.

3.6.1 Safety Screen Barriers

Hussong Mfg. highly recommends to use black painted safety barriers in outdoor installaons. Other screen barriers that incor-

porate a plated or pana nish are highly suscepble to oxidaon and discoloraon.

3.6.2 Requirements

• Calculate your roof overhang dimensions by following Figure 3.6 below.

• The connuous insulated building envelope and weatherproof membrane are not to be interrupted by gas stove installa-

on. See Figure 3.7.

• Gas stove operaon is approved from 40°F to 110°F.

• All wiring connecons shall be in accordance with outdoor requirements of NECA NFPA 70.

• All clearances and requirements in your appliance manual must be adhered to.

4.0 Gas Line Connecon

4.1 Gas Conversion

The gas conversion kit is sold separately.

ATTENTION: The conversion shall be carried out in accordance with the requirements of the provincial authories having juris-

dicon and in accordance with the requirements of the ANSI Z223.1 installaon code.

This replace is manufactured for use with natural gas. Follow the instrucons included with the conversion kit if converng to

propane.

4.2 Gas Line Installaon

CAUTION: Installaon of the gas line must only be done by a qualied person in accordance with local building codes, if any. If

not, follow ANSI Z223.1. Commonwealth of Massachuses installaons must be done by a licensed plumber or gas er.

NOTE: The appliance and its individual shuto valve must be disconnected from the gas supply piping system during any pres-

sure tesng of that system at pressures in excess of ½ psi (3.5 kPa). For test pressures equal to or less than ½ psi (3.5 kPa), the

appliance must be isolated from the gas supply piping system by closing its individual manual shut-o valve.

• A listed (and Commonwealth of Massachuses approved) 1/2” (13mm) tee handle manual shut-o valve and exible gas

connector are to be connected to the 1/2” (13 mm) control valve inlet. If substung for these components, please consult

local codes for compliance.

• This replace is equipped with a 3/8” (10mm) x 18” (457mm) long exible gas connector and manual shut-o valve.

• Run gas line into replace. The gas line should be run to the point of connecon where the shut-o valve and exible gas

line will connect. See Figure 2.1, LXL-22-L DIMENSIONS.

• Do not run gas line in a manner that would obstruct the oponal fan operaon.

• For high altude installaons, consult the local gas distributor or the authority having jurisdicon for proper rang meth-

ods.
