The  Sherwood  Home  Collection  of  fireplaces  have  been  tested  and  certified  for  use  with  SIMPSON  DURAVENT 
TYPE GS PIPE FOR GAS STOVES.  SECURITY CHIMNEY’S “SECURE VENT DIRECT VENT SYSTEM” and SELKIRK 
“METALBESTOS MDV VENT SYSTEM” kits are available for horizontal venting.  When using Simpson Duravent, it is 
recommended that, before installation, a bead of RTV High Temperature Silicone should be applied to each outer 
vent joint, and Mil-Pac to each inner joint.  When planning an installation, it will be necessary to select the proper 
length of vent pipe for the particular requirements.
