Q&A with TSSA – Drip Pocket Requirements

Q&A with TSSA – Drip Pocket Requirements

The B149-1-10 Natural Gas and Propane Installation Code requires that drip pockets be installed at the bottom of the riser or the final drop line serving the appliance.

Unfortunately, it always isn’t possible to place the drip pocket to meet the strict word wording of the code, resulting in red tags being issued for noncompliance.

John Marshall, Director, Fuels Safety Program, provides the following clarification to address this challenge.

Rooftop appliances – where it’s not possible to install the drip pocket in the final riser or final drop to the appliance

  • It’s acceptable to have the drip pocket in the horizontal piping before it enters the appliance casing
  • There must be a drip pocket on the riser to the roof
  • All other code requirements must be met

Manifolded commercial kitchen equipment

  • It’s not necessary to have a drip pocket at every piece of equipment, as long as there is one on the drop line or riser to the pipe manifold
  • All other code requirements must be met

      Unfortunately there isn't. You will need the appropriate Gas Technician certificate, G2 or G1 to install and activate these appliances.
