V + H = 40 feet (12.2 m) Max.

H = 20 ft. (6.096 m) Max.

Example: If 20 feet of (H) horizontal vent run is needed, then 4 feet minimum of (V) vertical vent will be required.

This table shows a 1 (V) to 5

(H)ratio. For every 1 foot of

(V)vertical, you are allowed 5 feet of (H) horizontal run, up to a maximum horizontal run of 20 feet.

*Use Firestop/Spacer SV4.5HF or SF4.5HF when using Secure Vent or Secure Flex respectively. Use Firestop/Spacer SV4.5HF5 or SF4.5HF5 when using Secure Vent or Secure Flex on horizontal vent runs for the MPLDV35/40/45 with a center line lower than 48” (1219 mm) above the fireplace top wrapper surface. In all cases the firestop/spacer provided with the termination may be used with the termination, frame to 5” clearance where applicable.
