Over the years Enefen has created and worked with manufacturers and installers to provide designs which comply with B149 and local regulations, address safety concerns, and improve energy efficiency. Design codes have been developed and are made available to customers through our client portal at nfnportal.com.
To see which design works for you go to nfnportal.com and choose "Request a Quote / Start a Field Approval" section. After giving us some basic information you can choose to look at P&ID's when you click on the "DIN" (Design Identification Number) button. It will ask you to further define what you are wanting in order to narrow the search for the correct drawing.
To ensure you have a current design which meets compliance, request a Field Approval with a "Design Approval in Principle" P.Eng. stamped drawing before you build.
How does design relate to a Field Approval?
B149.3 addresses the "Field Approval of Fuel-Related Components on Appliances and Equipment".
B149.1 addresses "Natural Gas and Propane Installation Code".
So in order to acquire an approved appliance the design must pass B149.3 code before you inspect the installation as required by B149.1.
How is it money can be saved with an in-house ENEFEN set of drawings?
The 1st step in the ENEFEN Field Approval process is a review of the drawings for functionality and component compliance. For example, B149 regulation requires that certified products are being used when readily available in the marketplace. This process is called approving the "Design in Principle" and conveys that at the time of the review the design met federal, municipal and local gas and safety codes and regulations. When choosing an in-house design this process has already been completed, so it reduces the amount of time and expense. You will also move immediately to the queue for inspection scheduling.
ENEFEN will also sign and stamp the P&ID for construction purposes, which saves you from having to outsource this prerequisite. We'll make sure the design matches with your process requirements. And, not only will we make sure that your average process load is taken under consideration, but we also look at special circumstances during:
System Start Up
System Warm Up
Refractory Cure Operation
Issues we review include access, ambient and environmental. Enefen also will review plant specific standards with gas safety code (CSA B149.3) requirements for any existing contradictions. And, because we have experience we know there is also Murphy's Law in form of process upsets, power outages or emergency shutdowns (ESD) which must be resolved even in the middle of the winter, during holidays and at midnight, which effect your system.
Our years of experience and the knowledge of our team makes it possible for us to put all the parameters together in an organized project and give you the results you need for an efficient, expeditious and exceptional process. A Professional Engineer stamps the drawings and is accountable for the results. With more than 35 years of experience, we also provide added peace of mind with recommendations for greater worker and community safety as well as greater efficiency.
Just look for our stamp - it's the "e".
YOUR THERMAL ENERGY AND COMBUSTION EQUIPMENT SHOULD WORK FOR YOU ......
