vPreparing 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 Chimneys™, or Dura-Vent®.
•  Installation of  any  fireplace  or  vent  system  component  not 
manufactured or approved by Lennox Hearth Products, Security 
Chimneys or 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) -   0 (0mm)
Rear corners to enclosure (from standoffs) -   0 (0mm)
Top to header (from standoffs) -   0 (0mm)
Bottom of unit to floor -   0 (0mm)
Edge of door glass to side wall and side trim -  6-1/4” (159mm)
Back to enclosure (from standoffs) -   0 (0mm)
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. 
wwFigure 1
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 22  for 
allowable pipe configurations.
