PLANNING YOUR INSTALLATION
QUESTIONS TO ASK THE LOCAL BUILDING OFFICIAL
Correct installation is c r itical a nd imperative for reduc ing
fire hazards and perilous con ditions that c an ar ise when
gas appliances func tion im pr operly. T he app liance m ust
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 lice nsed gas fitter or plumber m ay be required to install this appliance. Check with your local buildi ng 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
CLEARANCES TO COMBUSTIBLE MATERIALS
These appliances can be installed in most residential room
configurations , parallel to a rear or adjac ent wall, or in an
alcove that allo ws for the m inim um c learanc es to com bus tible surfaces. Yo ur local buildi ng inspector s hould 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 determ ined through t he safety cert ification of this un it,
a minimum clearance to combustible materials must be
maintained around specific areas of the gas appliance.
(See Figures 1, 2 and 3)
The clearances listed here are minimum distances and
only apply in the configuratio n shown. Do not use clearances from one installation configur ation with cleara nces
from another to obtain closer clearances.

EXAMPLES OF VENTING INSTALLATION APPLICATIONS
Model: L30 BF-2 (B-Vent) Venting Requirements
Approved for vertical termination only.
Venting Configuration Requirements:
A minimum of 5 feet vertical pipe is required to vent the
appliance. Lengthy horizontal pipe runs require sufficient
length of vertical pipe to deliver adequate draft. Use the
table above as a guide in planning your installation. The
use of multiple 45° or 90° elbows should be compensated by providing a ddi tio nal vertical pipe run .
This appliance has a 4” B-Vent flue collar and may be
installed with listed B-Vent piping and components.
Refer to the pipe manufacturer’s installation instructions
for specific requirements for their product. Maintain
proper cle arances to com bustible m aterials as spec ified
by the pipe manufacturer. W henever vent pipe is run
horizontally, maintain a minimum 1/4” ri se per foot. Exterior B-Vent exhaust systems should be enclosed in a
chase to avoid rapid cooling of exhaust gases in the
vent. Suc h cooling c ould produce c ondensati on of flue
gases or ex haust gas spi llage. The use of a chase is
highly recommended in colder climates.
VERTICAL VENT TERMINATION REQUIREMENTS
The vent termination clearances above the high side of an
angled roof is follows:

INSTALLATION
GAS SUPPLY HOOKUP
If using pipe other than black iron pipe see NFPA 54-National
Fire Protection Association / ANSI Z223.1-American National
Standards Institute; and local code for specific requirements
for the type of pipe used. Alternative gas piping systems such
as CSST may be used subject to local code and proper sizing.
This appliance is equipped with a flexible gas line and
fitting for a gas supply line connection. Connection can
be made using either the 3/8” NPT male fitting or, by removing the fitting, t o the flex line 3/8” female f lare. The
flex line can be routed to the gas supply through either
the pedestal bottom or through the rear pedestal cover
depending upon the orientat ion of the supply line. Som e
areas may have certain restrictions against the use of
flexible gas lin es. Chec k local co des. T he gas a pplia nce
control valve has a 3 /8” NPT fem ale type inlet for the gas
supply line, if hard plumbing is requir ed.
If the gas supply will b e routed to the appl iance from the
rear, the flexible g as line f or hook up is rea dil y acc ess ible.
If the gas supply will b e routed to the appliance through
the flooring, remove th e rear panel. Redirect the flex ible
gas line through the large hole in the c enter of the pedestal base for gas supply connection.
A gas supply line must be run to the appliance by a qualified professional. The plumbing of the gas line must
comply with National Standards; NFPA 54-National Fire
Protection Associatio n / ANSI Z223.1-American N ational
Standards Institute; and loca l cod e.
Gas piping must not run in or throu gh air ducts, clothes
chutes, chimneys or gas vents, dum b waiters or elevator
shafts.
Piping should be sloped 1 / 4” per 15 feet (6mm per
4.6m) upward toward th e meter from the appliance. The
piping must be supported at proper intervals every 8 to
10 ft. (2.4m to 3.1m) using suitable hangers or straps.
The gas supply line must be purged of air before it is
connected to the appliance.
An accessible, approv ed shut-off valve m ust be installed
upstream of any conn ector so that the app liance may be
isolated to allow service, removal, and replacement
(within six feet of the applianc e per NFPA 54, or twelve
inches in some c odes). A shut-off valve is provided with
this appliance.
IMPORTANT: In case emergency shut-off is required,
shut off main manual gas valve and disconnect main
power to appliance. These devices should be properly
labeled by the installer.
PRESSURE TESTING:
• The appliance main gas valve must be disconnected from the gas
supply piping system during any pressure testing of that system at
test pressures in excess of *1/2 psi (3.5 kPa).
PAGE 8
• The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than *1/2 psi (3.5 kPa).
Make the connection t o the gas supply line us ing the
correct fitting required to the shut-off valve.
Install a drip leg where condensates might accumulate. Sediment traps, lik e drips an d col lection t ees, ar e
required to be installed. Traps collect moisture and
intercept and hold foreign objects which might block
orifices and valves. A drip leg should be installed in
vertical pipe runs to the appliance.
Supply Line Size Requirements
The proper gas line diameter must be used to run
from the supply regulator (at the gas company meter )
to the appliance. Never use galvanized or plastic
pipe. Refer to the table below for suggested si zing of
the gas supply line.

11.0” W.C. for LP gas (propa ne) and use an ap proved
leak detection solut ion to test f or the tightn ess of each
pipe connection joint.
IMPORTANT: All connections must be checked for leaks with
a leak detector or soa py wat er solu tio n. Nev er chec k f or gas
leakage with an open flame!
