Pressure Switch Tube Installation (Category 3 Only)
When installing a category 3 (or greater) DaVinci fireplace, the pressure switch tube will need to be
installed into the center exhaust vent starter section. It cannot be pre-installed at the factory because the
master module is always on one side and the vent starter section on the secondary module. To install the
pressure switch tube, follow the directions below.
The pressure switch tube is critical to fireplace operation. If it is damaged, installed incorrectly, or
omitted, the fireplace will not operate or create a safety hazard.
1. The fireplace should be in place with the modules connected together. We recommend installing the
pressure switch tube prior to installing vent and framing over the fireplace to allow for maximum access.
2. The pressure switch is shipped lock-tied to the top of the master module. Carefully cut the lock-tie and
route the pressure switch tube to the center exhaust vent starter section.
DO NOT BEND THE TUBING AT A SHARP ANGLE – KINKS/HOLES WILL DISABLE THE FIREPLACE.
3. Insert the tube into the pre-drilled hole on the starter section. It should insert approximately 1” to 2”. Attach
the tube to the vertical stand with a lock tie (this prevents the tube from pulling out of the starter section.
Do not cut this lock-tie,
it secures the tube.
Cut the lock-ties
on the coil of tube.
Insert the tube 1” to 2”
into the starter section.
Secure the tube
with a lock-tie.
