Can I vent multiple heaters with one SideShot?
Yes. You will need to add an MAC1E interlock control to support the second appliance. It will interface with the UC1 control allowing you to interlock two individual appliances with one SideShot. Both appliances will need to share a common manifold or vent connector prior to the inlet of the SideShot. The total equivalent length of allowable pipe for a SideShot is fifty feet. Each elbow must be counted as ten feet. So the actual linear length of vent pipe is usually less than fifty feet. There is also a BTU/hr input limit that may not be exceeded. You can check the sizing table on-line or you can contact Tjernlund Products for assistance, 1-800-255-4208.
