Chimney Pipe and Anchor Plate:

Class “A” HT 2100 All Fuel 6 inch Chimney Pipe is required for optimum performance and must maintain a 2 inch clearance from 

combustibles.  The Shelter Furnace will ship with an anchor plate and four #10 ¾” galvanized screws with washers and gaskets.  If the 

anchor plate provided with your furnace does not fit your chimney type, please call our toll free number, 1-800-875-4788 for assistance. 
IMPORTANT: Please keep in mind that different chimney manufacturers’ pipe will not interchange with other brands.  A tube of high-temp 

silicone caulk is included with your furnace.  Before using the silicone to install the anchor plate to the top of your Shelter Furnace, 

ensure the chimney you purchased will fit the anchor plate.

Guy wire brackets are attached to the sides of the Shelter Furnace.  A heavy gauge of stainless steel wire can be purchased from your 

store to use as guy wire to help support your chimney.  Attach the appropriate chimney pipe lengths to the adaptor plate finishing with a 

chimney cap.  IMPORTANT: Your furnace requires its own chimney system and cannot share a flue with any other appliance.  DO NOT 

USE GALVANIZED OR BLACK PIPE TO VENT YOUR FURNACE.

INSTALLING THE ANCHOR PLATE:
