Summary

Pottstown's Fire Code amendment, Section 603.4.2, requires a permit before installing any unvented, gas-fired space heater and mandates a carbon monoxide detector mounted near the unit. The heater must also carry an oxygen depletion sensor that shuts it down automatically if oxygen levels drop, and its gas line must be color-coded yellow.

Section 603.4.2. Unvented Space Heaters; Gas-Fired. All gas-fired appliance installations shall require a permit prior to installation. The applicant must submit a sketch that demonstrates the location of the heater(s) and pipe routings. In addition, a description of the gas supply must be submitted. All gas-fired heaters must have an oxygen depletion sensor (ODS) ignition system that will enable the unit to shut down in the event of oxygen depletion. All piping shall be color-coded, with a yellow pipe indicating the gas line, and a carbon monoxide detector shall be mounted at an appropriate location in relating to the location of the heater. This section shall apply to all existing and new gas-fired appliance installations.

Full Breakdown

2, Unvented Space Heaters; Gas-Fired, is one of the amendments added under § 203 of Part 2 (International Fire Code) in Chapter 7, Fire Prevention and Fire Protection, adopted by Ordinance 2020 (May 8, 2006) and amended by Ordinance 2045 (November 13, 2007). Before an owner can install this type of heater, the Licensing and Inspections Department requires a permit application that includes a sketch showing the heater's location and pipe routing along with a description of the gas supply. The heater itself must carry an oxygen depletion sensor (ODS) ignition system so it shuts down automatically if the oxygen level in the room drops, and the gas piping must be color-coded yellow so an inspector or resident can identify it at a glance.

The section also requires a carbon monoxide detector mounted at an appropriate location relative to the heater, and it applies to both existing installations already in place and any new ones going forward. This is a narrower duty than a whole-house smoke-and-CO-alarm mandate: it attaches specifically to unvented, gas-fired space heaters rather than every dwelling, though any home relying on one of these units for supplemental heat, common in some of the Borough's older housing stock, needs a permitted installation with a working detector in place.

Violations & Fines

Installing an unvented gas-fired heater without a permit, without an ODS shutoff, or without the required carbon monoxide detector is a Fire Code violation. Since Part 2 sets no separate fine, Chapter 1, § 215 governs: $50 to $1,000 plus prosecution costs, up to 30 days in default of payment, and each day uncorrected counts as a new offense.

Frequently Asked Questions

Does Pottstown require a carbon monoxide detector in every home?
The Fire Code amendment at Section 603.4.2 requires one specifically where an unvented, gas-fired space heater is installed, mounted near the unit, along with an oxygen depletion sensor. It does not set a blanket CO-detector mandate for every dwelling regardless of heating equipment.
Do I need a permit to install a gas space heater in Pottstown?
Yes. Section 603.4.2 requires a permit application showing the heater's location, pipe routing and gas supply before installation, and the requirement applies to existing units as well as new ones.
What is an oxygen depletion sensor and why does Pottstown require one?
It is an ignition safety device that automatically shuts down an unvented gas heater if the oxygen level in the room falls too low. Section 603.4.2 requires every unvented, gas-fired heater in the Borough to have one, paired with a nearby carbon monoxide detector.
