Venting - Valor Legend G4 780IN Installation & Operating Instructions Manual

Typical Vent Installation
See list of approved Venting Accessories on page 35 of this manual.
NOTE: Flexible co-linear vent pipes may only be installed into existing non-
combustible solid-fuel burning fireplaces and chimneys.
Vent Location
The vent terminal must be located through the
roof. This direct vent appliance is designed to
operate when an undisturbed airflow hits the
outside vent terminal from any direction.
Check local codes for allowable vertical vent
termination.

Minimum vertical height 10 ft (measured to bottom of termination)
Maximum horizontal run 4 ft (measured center to center of pipe)

Venting Notes
Where possible, avoid joining flex pipes. If joints
are required, use a approved connector and seal
joints with RTV high temp sealant.
Horizontal offset is permissible to allow for
routing around masonry projections. Avoid
bending flex pipe over a 45 degrees radius
