Woodbridge Fireplace Inc DVI 750, Installation And Operating Instructions Manual

Use only new black iron or steel pipe. 
Internally  tinned  copper  or  copper 
tubing  can  be  used  per  National 
Fuel  Code,  section  2.6.3,  providing 
gas  meets  hydrogen  sulfide  limits, 
and  where  permitted  by  local  codes. 
Gas  piping  system  must  be  sized  to 
provide minimum inlet pressure (listed 
on data plate) at the maximum flow rate 
(BTU/hr).  Undue  pressure  loss  will 
occur if the pipe is too small.

CAUTION

INSERT INSTALLATION 

CHECK GAS TYPE

Use proper gas type for the insert you are installing. If you have conflicting gas type, do not install insert. See dealer where 
you purchased the insert for proper insert according to your gas type.

INSTALLING GAS PIPING TO INSERT LOCATION

For  propane/LP  units,  never  connect  insert  directly  to  the  propane/LP  supply.  This 
burner system requires an external regulator (not supplied). Install the external regulator 
between the burner system and propane/LP supply. 

CAUTION 

A qualified installer or service person 
must connect appliance to gas supply. 
Follow all local codes.

INSTALLATION ITEMS NEEDED

Before installing insert and burner system, make sure you have the items listed below.
• External regulator (supplied by installer)  •  Piping (check local codes)

• Sealant (resistant to propane/LP gas)

• Test gauge connection*

• Sediment trap (optional but recomended)

• Tee joint

• Pipe wrench

• approved flexible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certified equipment shutoff valve with

For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce incoming 
gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do not reduce incoming 
gas pressure, burner system regulator damage could occur. Install external regulator with the vent pointing down as shown 
in

Pointing the vent down protects it from freezing rain or sleet.
