Preparing Your Ravelle™ 30 Fireplace For Installation
Read all instructions before beginning your installation. If instructions
have not been read carefully, your installation could void your warranty
and may create a serious fire, health, or other safety hazard.
The Lennox Hearth Products warranty will be voided if one of the fol-
lowing occurs:
• Installation of any damaged fireplace or vent system compo-
nent.
• Unauthorized modification of the direct vent system.
• Installation other than as instructed by Lennox Hearth Products,
Security™, or Simpson Dura-Vent.
• Installation of any fireplace or vent system component not
manufactured or approved by Lennox Hearth Products, Security
or Simpson Dura-Vent.
When planning the installation for your Ravelle 30 gas fireplace, it's
necessary to consider the following:
• Where the unit is to be installed
• The vent system configuration to be used
• Gas supply (NG or LP)
• Electrical wiring
• Framing and finishing
• Optional accessories
Clearances to Combustibles
Minimum clearances include any projections such as shelves, window
sills, mantels, spacers/standoffs or surfaces to combustible construction
etc. above the appliance. Paint or lacquer used to finish the mantel
must be heat resistant in order to avoid discoloration.
Minimum clearances to combustible materials in inches:
Front corners to enclosure (from standoffs) -
Rear corners to enclosure (from standoffs) -
Top to header (from standoffs) -
Bottom of unit to floor -
Edge of door glass to side wall and side trim -
Back to enclosure (from standoffs) -
Mantel: The drawing at the lower right shows the minimum distances
from the base of the fireplace to combustible mantel and facing mate-
rial. Combustible materials may be placed above and withing the shaded
areas. If your fireplace has an arched face, the combustible mantel fac-
ing material may curve with the arch of the face as long as a minimum
distance of 10" (254mm) is maintained between the top of the face and
the combustible facing material.
Hearth Protection: If the vertical distance from the base of a Ravelle
30 gas fireplace to a combustible surface is less than 1", then a hearth
protection is required in front of the unit. The required hearth protec-
tion must extend 10" (254mm) out from the front of the unit with a
width of 41" (1041mm) and include a minimum of 1/2" (13mm) thick
non-combustible material. If the vertical distance from the base of the
unit to the combustible surfaces is 1"(25mm) or greater, then no hearth
protection is required.
Pipe Clearances: On all vertical runs of pipe, a 1" (25mm) clearance
between the direct vent pipe and combustibles must be maintained.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
When an 18" (457mm) or longer section of pipe is installed vertically,
directly off the top of the unit, then any horizontal run of pipe must
maintain clearances to combustibles of 2" (51mm) on the top and 1"
(25mm) on the sides and bottom. When less than 18" (457mm) of pipe
is installed vertically, directly off the top of the unit, then any horizontal
run of pipe must maintain clearances to combustibles of 6" (152mm)
on the top and 1" (25mm) on the sides and bottom. See Page 17 for
allowable pipe configurations.
