General Notes Regarding Conversion
The Ventana can be converted before or after installation into a wall. If converting after the fi replace is installed and
enclosed into the wall, the access to the minimum rate by-pass screw will require the removal of the burner module.
As well, the earlier version of the burner fi xing method to the burner module will require that the burner module be
removed—see section
Burner
.
There are two versions of the Ventana fi replace with respect to the manifold pressure regulation. Earlier versions
have a separate, convertible regulator that does not require a gas supply or a manometer to convert. Later versions
have a regulator integral with the control valve and require a gas supply and manometer to complete the conversion.
See section
Manifold Pressure
to determine which version you have.
Conversion Procedure
The conversion procedure will vary according to three factors.
•
Whether the heater is already installed or not;
•
Whether the burner mounting is considered an earlier model or later model;
•
Whether the heater has a separate convertible regulator or a regulator integral to the valve.
The burner module assembly does not need to be removed from the
heater in the following case:
•
The conversion is done before the heater installation,
AND
•
The burner mounting is a later model (fi xed to the burner tray from
the top side).
In ALL other cases, the burner module must be removed to proceed to
the conversion.
1. Remove the window, logs/pack and ceramic bricks (if installed) from the fi rebox.
2. Shut-off gas if unit is already installed and disconnect gas line at the regulator or valve depending on model.
3. If the burner needs to be removed, remove the cast fret, front and rear brick supports—see fi gure 1.
4. Proceed to the following sub-sections.
